3Recent progress in thermoelectric materials显示文摘Direct conversion of heat into electricity through advanced thermoelectric(TE)materials has been one of the most attractive solutions to the severe environmental and energy issues facing humanity.In recent years,great progress has been made in improving their dimensionless figure of merit(ZT),which determines the conversion efficiency of TE devices.ZT is related to three‘‘interlocked’’factors—the Seebeck coefficient,electrical conductivity,and thermal conductivity.These three factors are interdependent in bulk TE materials,and altering one changes the other two.The difficulty in simultaneously optimizing them caused TE research to stagnate,until great reductions in thermal conductivity were both theoretically and experimentally proven in nanomaterials in 1993.In this review,we first introduce some TE fundamentals and then review the most recently improvements in ZT in different kinds of inorganic and organic TE materials,which is followed by an investigation of the outlook for new directions in TE technology.Chao Han Zhen Li Shixue Dou 2014Chinese Science Bulletin2014,59,18:9

5Confining MOF-derived SnSe nanoplatelets in nitrogen-doped graphene cages via direct CVD for durable sodium ion storage显示文摘Tin-based compounds are deemed as suitable anode candidates affording promising sodium-ion storages for rechargeable batteries andhybrid capacitors.However,synergistically tailoring the electrical conductivity and structural stability of tin-based anodes to attain durablesodium-ion storages remains challenging to date for its practical applications.Herein,metal-organic framework(MOF)derived SnSe/C wrappedwithin nitrogen-doped graphene(NG@SnSe/C)is designed targeting durable sodium-ion storage.NG@SnSe/C possesses favorable electricalconductivity and structure stability due to the'inner'carbon framework from the MOF thermal treatment and'outer'graphitic cage from thedirect chemical vapor deposition synthesis.Consequently,NG@SnSe/C electrode can obtain a high reversible capacity of 650 mAh·g^-1 at 0.05 A·g^1,a favorable rate performance of 287.8 mAh·g^1 at 5 A·g^1 and a superior cycle stability with a negligible capacity decay of 0.016%percycle over 3,200 cycles at 0.4 A·g^1.Theoretical calculations reveal that the nitrogen-doping in graphene can stabilize the NG@SnSe/Cstructure and improve the electrical conductivity.The reversible Na-ion storage mechanism of SnSe is further investigated by in-situ X-raydiffraction/ex-s/tu transmission electron microscopy.Furthermore,assembled sodium-ion hybrid capacitor full-cells comprising our NG@SnSe/Canode and an active carbon cathode harvest a high energy/power density of 115.5 Wh·kg^-1/5,742 W·kg^-1,holding promise for next-generationen ergy storages.Chen Lu Zhenzhu Li Zhou Xia Haina Ci Jingsheng Cai Yingze Song Lianghao Yu Wanjian Yin Shixue Dou Jingyu Sun Zhongfan Liu 2019Nano Research2019,12,12:7

Advanced functional nanomaterials and relevant nanotechnologies are playing a crucial role and showing promise in resolving some energy issues. In this view, we focus on recent advances of functional nanomaterials in clean energy applications, including solar energy conversion, water splitting, photodegradation, electrochemical energy conversion and storage, and thermoelectric conversion, which have attracted considerable interests in the regime of clean energy.Jinyan Xiong Chao Han Zhen Li Shixue Dou 2015Science Bulletin2015,60,24:6
7Synergistic impact of cocatalysts and hole scavenger for promoted photocatalytic H2 evolution in mesoporous TiO2–NiSx hybrid显示文摘Photocatalytic solar energy conversion to hydrogen is sustainable and attractive for addressing the global energy and environmental issue. Herein, a novel photocatalytic system (NiS/Ni3S4 cocatalysts modified mesoporous TiO2) with superior photocatalytic hydrogen evolution capability through the synergistic impact of NiS/Ni3S4 (NiSx) cocatalyst and efficient hole scavenger has been demonstrated. The photocatalytic hydrogen evolution of TiO2-NiSx hybrids with the different content of NiSx and upon different organic hole scavengers was both investigated. The hybrid of TiO2 decorated with 3%(mole ratio of Ni^2+) NiSx cocatalyst in methanol solution showed the optimal photocatalytic hydrogen evolution rate of 981.59 μmol h^-1 g^-1 which was about 20 times higher than that of bare mesoporous TiO2. Our results suggested that the boosted hydrogen production performance is attributed to both the improved photoinduced electrons migration between NiS and Ni3S4 in cocatalyst and the high hole captured efficiency by hole scavengers of methanol.Yi Wei Gang Cheng Jinyan Xiong Jiaxin Zhu Yixin Gan Mengmeng Zhang Zhen Li Shixue Dou 2019Journal of Energy Chemistry2019,28,5:3
8Confining TiO_2 Nanotubes in PECVD-Enabled Graphene Capsules Toward Ultrafast K-Ion Storage: In Situ TEM/XRD Study and DFT Analysis显示文摘Titanium dioxide(TiO2) has gained burgeoning attention for potassium-ion storage because of its large theoretical capacity,wide availability,and environmental benignity.Nevertheless,the inherently poor conductivity gives rise to its sluggish reaction kinetics and inferior rate capability.Here,we report the direct graphene growth over TiO2 nanotubes by virtue of chemical vapor deposition.Such conformal graphene coatings effectively enhance the conductive environment and well accommodate the volume change of TiO2 upon potassiation/depotassiation.When paired with an activated carbon cathode,the graphene-armored TiO2 nanotubes allow the potassium-ion hybrid capacitor full cells to harvest an energy/power density of 81.2 Wh kg-1/3746.6 W kg-1.We further employ in situ transmis sion electron microscopy and ope rando X-ray diffraction to probe the potassium-ion storage behavior.This work offers a viable and versatile solution to the anode design and in situ probing of potassium storage technologies that is readily promising for practical applications.Jingsheng Cai Ran Cai Zhongti Sun Xiangguo Wang Nan Wei Feng Xu Yuanlong Shao Peng Gao Shixue Dou Jingyu Sun 2020Nano-Micro Letters2020,12,9:2

10Research Progress of Electromagnetic Properties of MgB2 Induced by Carbon-Containing Materials Addition and Process Techniques显示文摘For the high transition temperature(Tc) and low cost taking both raw materials and fabrication process into account,MgB2 has been a competitive candidate to replace the conventional NiTi superconductor for high-temperature application in fault current limiters,transformers,motors,magnetic resonance imaging,adiabatic demagnetization refrigerators,generators,etc.The carbon-containing materials addition induced high critical current density(Jc) is reviewed based on their influences on the upper critical field(Hc2),flux pinning force,and connectivity.The doping effects were compared in the overview focusing on SiC,organic dopants,and graphene-related dopants.SiC doping is featured for the high-field critical current density,which is caused by the increased Hc2 attributed to the substitution of carbon on boron site and the strong flux pinning force offered by the nanosized secondary phases in the MgB2 matrix.Organic dopants have the advantage over SiC dopant for their relatively homogeneous distribution in the MgB2 matrix based on wet mixing of the organics and the raw boron powders.Low doping level of two-dimensional materials can improve the superconducting properties in all measured fields because of the combined advantages of carbon substitution effect and grain connectivity.MgB2 fabricated with carbon-encapsulated boron also introduces strong flux pinning centers in MgB2,which show weak destruction of the connectivity of the MgB2 grains as reflected by the low-magnetic-supercurrent behavior.High-pressure treatment and diffusion method can fabricate highdensity MgB2 superconductors with better connectivity and increase the Jc compared with the in situ and ex situ methods.Jiancheng Li Haobo Liu Ying Li Chuanbing Cai Shixue Dou Wenxian Li 2020Acta Metallurgica Sinica(English Letters)2020,33,4:1
11Non-precious metal electrocatalysts for two-electron oxygen electrochemistry: Mechanisms, progress, and outlooks显示文摘Hydrogen peroxide (H_(2)O_(2)) is a valuable chemical for a wide variety of applications. The environmentally friendly production route of the electrochemical reduction of O_(2)to H_(2)O_(2) has become an attractive alternative to the traditional anthraquinone process. The efficiency of electrosynthesis process depends considerably on the availability of cost-effective catalysts with high selectivity, activity, and stability.Currently, there are many outstanding issues in the preparation of highly selective catalysts, the exploration of the interface electrolysis environment, and the construction of electrolysis devices, which have led to extensive research efforts. Distinct from the existing few comprehensive review articles on H_(2)O_(2) production by two-electron oxygen reduction, the present review first explains the principle of the oxygen reduction reaction and then highlights recent advances in the regulation and control strategies of different types of catalysts. Key factors of electrode structure and device design are discussed. In addition,we highlight the promising co-production combination of this system with renewable energy or energy storage systems. This review can help introduce the potential of oxygen reduction electrochemical production of high-flux H_(2)O_(2) to the commercial market.Yuhan Wu Jianhui Sun Shixue Dou Jingyu Sun 2022Journal of Energy Chemistry2022,31,6:1
12Bifunctional flame retardant solid-state electrolyte toward safe Li metal batteries显示文摘Solid polymer electrolytes(SPEs)are one of the most promising alternatives to flammable liquid electrolytes for building safe Li metal batteries.Nevertheless,the poor ionic conductivity at room temperature(RT)and low resistance to Li dendrites seriously hinder the commercialization of SPEs.Herein,we design a bifunctional flame retardant SPE by combining hydroxyapatite(HAP)nanomaterials with Nmethyl pyrrolidone(NMP)in the PVDF-HFP matrix.The addition of HAP generates a hydrogen bond network with the PVDF-HFP matrix and cooperates with NMP to facilitate the dissociation of Li TFSI in the PVDF-HFP matrix.Consequently,the prepared SPE demonstrates superior ionic conductivity at RT,excellent fireproof properties,and strong resistance to Li dendrites.The assembled Li symmetric cell with prepared SPE exhibits a stable cycling performance of over 1200 h at 0.2 m A cm^(-2),and the solid-state LiFePO_4||Li cell shows excellent capacity retention of 85.3%over 600 cycles at 0.5 C.Qiang Lv Yajie Song Bo Wang Shangjie Wang Bochen Wu Yutong Jing Huaizheng Ren Shengbo Yang Lei Wang Lihui Xiao Dianlong Wang Huakun Liu Shixue Dou 2023Journal of Energy Chemistry2023,,6:1

16Perspective on solid‐electrolyte interphase regulation for lithium metal batteries显示文摘The solid‐electrolyte interphase(SEI)generated between the electrode and the electrolyte strongly influences the performance of batteries.As the most at-tractive next‐generation energy storage system with ultrahigh energy density,the development of lithium metal batteries(LMBs)has been greatly plagued by the uncontrollable lithium(Li)dendrite and serious electrolyte decom-position resulting from the self‐derived unstable SEI with poor properties.In this perspective,the recent progress of regulating the nature and composition of the SEI to stabilize the Li metal in LMBs is summarized,followed by a discussion of the formation mechanism and the property of the SEI.The strategies for constructing a stable SEI are summarized,for example,design of a compatible electrolyte with the anode,adding self‐sacrificing additives or solvation control additives,and the regulation of nonfaradaic electric ad-sorption and desorption progress.Finally,the guideline for the rational design of the SEI is proposed.Mingguang Wu Yong Li Xinhua Liu Shichun Yang Jianmin Ma Shixue Dou 2021SmartMat2021,2,1:1
