| 2 | Preparation, characterization and electrochemical properties of mesoporous LiFe_(0.99)Mo_(0.01)PO_4/C显示文摘A mesoporous LiFe0.99Mo0.01PO4/C composite was synthesized by the sol-gel method using (NH4)2MoO4 as a doping starting material. The formation of conductive carbon, metal doping and mesopores was achieved simultaneously in the prepared material. The characterizations of crystal structures and microstructures were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), extended X-ray-absorption fine-structure (EXAFS) and X-ray-absorption near-structure spectroscopy (XANES), while the surface area was determined using N2 adsorption techniques. Cyclic voltammetry (CV) and charge-discharge cycling performance were used to characterize its electrochemical properties. The sample possessed uniformly distributed mesopores with an average pore size of 4 nm, and the specific surface area was about 69.368 m2/g. The results show that the reversible capacity of mesoporous LiFe0.99Mo0.01PO4/C is about 160 mAh/g at 0.1C, 135 mAh/g at 1C and 90 mAh/g at 5C, respectively. The capacity fading is neglectable. | YU Chunyang WANG Zhongli CHEN Yu XIA Dingguo CHU Wangsheng WU Ziyuc | 2009 | Rare Metals2009，28，4： | 4 |
| 3 | Room-temperature ligancy engineering of perovskite electrocatalyst for enhanced electrochemical water oxidation显示文摘Perovskite oxides are significant candidates to develop electrochemical catalysts for water oxidation in consideration of their high catalysis capacity,low costing and excellent stability.Rational design of coordination structure and overcoming poor electronic transport are regarded as critical factors for outstanding perovskite-based oxygen evolution reaction (OER) catalysts.Herein,we report a mild chemical oxidation method to realize ligancy engineering from strongly-correlated brownmillerite Sr2Co2O5 to perovskite phase Sr2Co2O5.5,along with abundant oxygen vacancies formation and greatly boosted electric conductivity,which helps to form the active species of Co hydroxide/oxide on the surface of catalysts.The coupling effect of catalytic kinetics and unimpeded electronic movement brings high OER activities in Sr2Co2O5.5 with a low onset potential and a small Tafel slope.Our work not only displays in-depth understanding into the relationship among catalysis performance and multiple physical degrees of freedom,but also paves a new path to develop high-efficient electrochemical catalysts. | Junchi Wu Yuqiao Guo Haifeng Liu Jiyin Zhao Haodong Zhou Wangsheng Chu Changzheng Wu | 2019 | Nano Research2019，12，9： | 4 |
| 4 | Asymmetricalπback-donation of hetero-dicationic Mo^(4+)-Mo^(6+)pairs for enhanced electrochemical nitrogen reduction显示文摘The breaking of nonpolar N≡N bond of dinitrogen is the biggest dilemma for electrocatalytic nitrogen reduction reaction(NRR)application,driving electron migration between catalysts and N≡N bond(termed“πback-donation”process)is crucial for attenuating interfacial energy barrier but still remains challenging.Herein,using density functional theory calculations,we revealed that constructing a unique hetero-dicationic Mo^(4+)-Mo^(6+)pair could effectively activate N≡N bond with a lying-down chemisorption configuration by an asymmetrical“πback-donation”process.As a proof-of-concept demonstration,we synthesized MoO_(2)@MoO_(3)heterostructure with double Mo sites(Mo^(4+)-Mo^(6+)),which are embedded in graphite,for electrochemical nitrogen reduction.Impressively,this hetero-dicationic Mo^(4+)-Mo^(6+)pair catalysts display more excellent catalytic performance with a high NH_(3)yield(60.9μg·h^(-1)·mg^(-1))and Faradic efficiency(23.8%)as NRR catalysts under ambient conditions than pristine MoO_(2)and MoO_(3).Operando characterizations using synchrotron-based spectroscopic techniques identified the emergence of a key^(*)N_(2)Hy intermediate on Mo sites during NRR,which indicates that the Mo sites are active sites and the NRR process tends to follow an associative mechanism.This novel type of hetero-dicationic catalyst has tremendous potential as a new class of transition metal-based catalysts with promising applications in electrocatalysis and catalysts for energy conversion and storage. | Hao Tan Qianqian Ji Chao Wang Hengli Duan Yuan Kong Yao Wang Sihua Feng Liyang Lv Fengchun Hu Wenhua Zhang Wangsheng Chu Zhihu Sun Wensheng Yan | 2022 | Nano Research2022，15，4： | 2 |

| 6 | Surface etching induced ultrathin sandwich structure realizing enhanced photocatalytic activity显示文摘Photocatalytic conversion efficiency is limited by serious charge carrier recombination. Efficient carrier separation is usually achieved by elegantly-designed multi-component structures connected by directional electric field. Herein, we developed a twodimensional(2 D) sandwich structure, as a new photocatalytic system, to realize high-efficiency carrier separation. This strategy integrated multifunction into a single structure for the first time, which successfully introduces a stable built-in electric field,realizing high-effective carrier separation. Besides, the carrier concentration is dramatically increased due to dimensional confinement. Benefiting from above synergic advantages, 2 D sandwich photocatalyst achieves the highest nitrogen fixation rate(435 μmol g^(-1) h^(-1)) in inorganic solid photocatalysts under visible light irradiation. We anticipate that 2 D sandwich photocatalyst holds promises for the application and expansion of 2 D materials in photocatalysis research. | Bo Yang Wentuan Bi Yangyang Wan Xiaogang Li Mingcan Huang Ruilin Yuan Huanxin Ju Wangsheng Chu Xiaojun Wu Linghui He Changzheng Wu Yi Xie | 2018 | Science China Chemistry2018，61，12： | 1 |
| 7 | Interfacial ion regulation on 2D layered double hydroxide nanosheets for enhanced thermal insulation显示文摘Exploring new strategies to broaden the upper/lower limit of thermal conductivity is of great interest to develop thermal management materials that can adapt to extreme environments.In this work,we employ an interfacial ion regulation to enhance the thermal insulation performance of 2D layered double hydroxide nanosheets.The introduction of interfacial ion enlarges the interplanar spacing of Co(OH)_(2) nanosheets from 4.64 to 8.05 ?,which reduces phonon scattering length perpendicular to the two-dimensional plane and leads to enhanced interlayer thermal insulation.The interfacial ion-regulated Co(OH)_(2)(named as Co(OH)_(2)-M^(x-)) exhibits 3-fold enhancement of thermal insulation through decreasing the thermal conductivity to as low as 0.15 W m^(-1) K^(-1),which is among the top values in 2D solid materials.We anticipate that interfacial ion regulation for 2D nanosheets paves a new avenue to break through the thermal insulation limit. | Chun Wang Hengyu Xu Han Cheng Hao Yu Si Liu Wenjie Wang Ruilin Yuan Hongfei Liu Tianpei Zhou Wangsheng Chu HengAn Wu Yi Xie Changzheng Wu | 2022 | Science China Chemistry2022，65，5： | 0 |
| 8 | Support induced phase engineering toward superior electrocatalyst显示文摘The phase transformation of catalysts has been extensively observed in heterogeneous catalytic reactions that hinder the long cycling catalysis,and it remains a big challenge to precisely control the active phase during the complex conditions in electrochemical catalysis.Here,we theoretically predict that carbon-based support could achieve the phase engineering regulation of catalysts by suppressing specific phase transformation.Taken single-walled carbon nanotube(SWCNT)as typical support,combined with calculated E-pH(Pourbaix)diagram and advanced synchrotron-based characterizations technologies prove there are two different active phases source from cobalt selenide which demonstrate that the feasibility of using support effect regulating the potential advantageous catalysts.Moreover,it is worth noting that the phase engineering derived Co_(3)O_(4)-SWCNT exhibits a low overpotential of 201 mV for delivering the current density of 10 mA/cm^(2)in electrocatalytic oxygen evolution reaction(OER).Also,it reaches a record current density of 529 mA/cm^(2)at 1.63 V(vs.RHE)in the electrocatalytic urea oxidation reaction(UOR),overwhelming most previously reported catalysts. | Beibei Sheng Dengfeng Cao Hongwei Shou Oyawale Adetunji Moses Wenjie Xu Yujian Xia Yuzhu Zhou Huijuan Wang Ping Wan Shuang Zhu Wangsheng Chu Xiaojun Wu Shuangming Chen Li Song | 2022 | Nano Research2022，15，3： | 0 |

| 10 | Sulfur-induced dynamic reconstruction of iron-nitrogen species for highly active neutral oxygen reduction reactions显示文摘The neutral oxygen reduction reaction(ORR)has attracted tremendous attention for its broad prospects in next-generation power storage systems.However,the extremely sluggish cathodic reaction process and the limited cognition of the reaction mechanism greatly hinder its practical application.Here,we demonstrate a dynamic reconstruction behavior induced by sulfur of the iron-nitrogen(Fe-Nx)species in neutral solution.Our developed FeS_(1)N_(3)-OH configuration effectively optimizes the reaction kinetics by regulating the adsorption energy of oxygen intermediates for central catalytic sites.Consequently,this structure exhibits over 363%enhancement in ORR mass activity compared to the pristine FeN_(4) sites under neutral electrolyte.Moreover,a neutral zinc-air battery assembled with this electrocatalyst reached an ultrahigh peak power density(81.2 mW cm^(−2)),robust stability(more than 100 h)as well as superior tolerance to extreme environments(operating between−20°C and 60°C),representing a critical breakthrough for neutral ORR exploration and application. | Wenjie Wang Tianpei Zhou Kai Zhang Chun Wang Xiang Shi Lin Wang Qinghua Liu Yang Wang Qiyang Jiao Guixin Ma Chen Ye Yi Xie Xiaojun Wu Wangsheng Chu Changzheng Wu | 2022 | Science China Chemistry2022，65，12： | 0 |
| 11 | Insights into the Ti^(4+) doping in P2-type Na_(0.67)Ni_(0.33)Mn_(0.52)Ti_(0.15)O_(2) for enhanced performance of sodium-ion batteries显示文摘Due to the sodium abundance and availability,sodium-ion batteries(SIBs)have the potential to meet the worldwide growing demand of electrical energy storage.P2-type sodium transition-metal layer oxides with a high energy density are considered as the most promising cathode materials for SIBs.We present here a detailed study of the enhanced rate capability and cyclic stability of the Ti-doped Na_(0.67)Ni_(0.33)Mn_(0.67)O_(2)cathode material.The combined analysis of ex-situ X-ray absorption fine structure(XAFS)spectroscopy,aberration-corrected high resolution transmission electron microscopy(AB-HRTEM)and X-ray diffraction(XRD)show that the strong Ti–O bond in the transition metal layers stabilizes the local structure,destroy the Na+-vacancy ordering and arrest the irreversible multiphase transformation that occurs during the intercalation/deintercalation process.Actually,Na_(0.67)Ni_(0.33)Mn_(0.52)Ti_(0.15)O_(2)exhibits a reversible capacity of 89.6 mA h g^(-1)even at 5 C,an excellent cyclability with 88.78%capacity retention after 200 cycles at 0.5 C.This study provides a better understanding in optimization of the design of high-energy cathode materials based on titanium doped layered oxides for SIBs. | Shi Tao Wei ZhouaDajun Wu Zhicheng Wang Bin Qian Wangsheng Chu Augusto Marcelli Li Song | 2021 | Journal of Materials Science & Technology2021，，15： | 0 |
