| 1 | Recent Advances in Single-Atom Electrocatalysts for Oxygen Reduction Reaction显示文摘Oxygen reduction reaction(ORR)plays significant roles in electrochemical energy storage and conversion systems as well as clean synthesis of fine chemicals.However,the ORR process shows sluggish kinetics and requires platinum-group noble metal catalysts to accelerate the reaction.The high cost,rare reservation,and unsatisfied durability significantly impede large-scale commercialization of platinum-based catalysts.Single-atom electrocatalysts(SAECs)featuring with well-defined structure,high intrinsic activity,and maximum atom efficiency have emerged as a novel field in electrocatalytic science since it is promising to substitute expensive platinum-group noble metal catalysts.However,finely fabricating SAECs with uniform and highly dense active sites,fully maximizing the utilization efficiency of active sites,and maintaining the atomically isolated sites as single-atom centers under harsh electrocatalytic conditions remain urgent challenges.In this review,we summarized recent advances of SAECs in synthesis,characterization,oxygen reduction reaction(ORR)performance,and applications in ORR-related H_(2)O_(2)production,metal-air batteries,and low-temperature fuel cells.Relevant progress on tailoring the coordination structure of isolated metal centers by doping other metals or ligands,enriching the concentration of single-atom sites by increasing metal loadings,and engineering the porosity and electronic structure of the support by optimizing the mass and electron transport are also reviewed.Moreover,general strategies to synthesize SAECs with high metal loadings on practical scale are highlighted,the deep learning algorithm for rational design of SAECs is introduced,and theoretical understanding of active-site structures of SAECs is discussed as well.Perspectives on future directions and remaining challenges of SAECs are presented. | Junxing Han Juanjuan Bian Chunwen Sun | 2020 | Research2020，，1： | 6 |
| 2 | Change of Cytokines in Chronic Hepatitis B Patients and HBeAg are Positively Correlated with HBV RNA, Based on Real-world Study显示文摘Background and Aims:The natural course of chronic hepatitis B virus(HBV)infection is widely studied;however,follow-up studies of the same patients are scanty.Here,we studied the dynamic changes of serum HBV RNA and cytokines in hepatitis B virus e antigen(HBeAg)-positive patients treated with entecavir(ETV)to explore the relationship between the HBV serum viral nucleic acids and host immunity.Methods:Thirty-three chronic hepatitis B patients who are HBeAg-positive,with high virus load(HBV DNA>20,000 IU/mL),and received standard nucleos(t)ide analogue(NA)antiviral therapy(ETV)for more than 48 weeks were included.The serum levels of HBV nucleic acids and selected cytokines were measured at 0,12,24,and 48 weeks respectively.Results:Serum HBV RNA could still be detected while serum HBV DNA had fallen below the detection limit in patients treated with ETV.There was a strong positive correlation between HBV RNA and HBeAg,with a concomitant decrease in the secretion of cytokines from type 1 helper T(Th1)/type 2 helper T(Th2)/interleukin(IL)-17 producing T(Th17)cells.IL-4 and IL-10 were the main cytokines negatively associated with serum HBV RNA.Conclusions:HBeAg can be used to reflect the load of HBV RNA indirectly,because serum HBV RNA has not been widely used in clinical practice.Meanwhile,serum IL-4 and IL-10 might be explored in combination with HBV RNA in guiding future clinical antiviral therapy. | Qiqi Zhang Hui Huang Aijun Sun Chunyan Liu Zhidong Wang Feifan Shi Wei Duan Xueying Sun Qi Wang Ping Sun Chunwen Pu Yong Zhang | 2022 | Journal of Clinical and Translational Hepatology2022，10，3： | 1 |

| 18 | Recent Progress in and Perspectives on Emerging Halide Superionic Conductors for All‑Solid‑State Batteries显示文摘Rechargeable all-solid-state batteries(ASSBs)are considered to be the next generation of devices for electrochemical energy storage.The development of solid-state electrolytes(SSEs)is one of the most crucial subjects in the field of energy storage chemistry.The newly emerging halide SSEs have recently been intensively studied for application in ASSBs due to their favorable combination of high ionic conductivity,exceptional chemical and electrochemical stability,and superior mechanical deformability.In this review,a critical overview of the development,synthesis,chemical stability and remaining challenges of halide SSEs is given.The design strategies for optimizing the ionic conductivity of halide SSEs,such as element substitution and crystal structure design,are summarized in detail.Moreover,the associated chemical stability issues in terms of solvent compatibility,humid air stability and corresponding degradation mechanisms are discussed.In particular,advanced in situ/operando characterization techniques applied to halide-based ASSBs are highlighted.In addition,a comprehensive understanding of the interface issues,cost issues,and scalable processing challenges faced by halide-based ASSBs for practical application is provided.Finally,future perspectives on how to design high-performance electrode/electrolyte materials are given,which are instructive for guiding the development of halide-based ASSBs for energy conversion and storage. | Kaiyong Tuo Chunwen Sun Shuqin Liu | 2023 | Electrochemical Energy Reviews2023，6，1： | 1 |

| 20 | Elucidating the diffusion pathway of lithium ions in superionic halide solid electrolytes Li_(2+x)Hf_(1-x)In_(x)Cl_(6) for all-solid-state lithium-metal based batteries显示文摘All-solid-state batteries(ASSBs) with inorganic solid-state-electrolytes(SSEs) have been regarded as the promising candidate for next-generation energy storage due to their high energy density and outstanding safety performance.However,the representative oxide and sulfide electrolytes suffer from low ionic conductivity and poor(electro)chemical stability,respectively.Herein,we report a series of new halide superionic conductors Li_(2+x)Hf_(1-x)In_(x)Cl_(6) with high ionic conductivity up to 1.05 mS cm^(-1) at 30 ℃ that are simultaneously stable to high voltage.By means of the characterization techniques and bond-valence site energy(BVSE) calculation,insights into the effect of the phase transformation and underlying ionic transport mechanism by In substitution for Hf in Li_(2)HfCl_(6) are provided.Importantly,with the increased amount of aliovalent substitution in Li_(2+x)Hf_(1-x)In_(x)Cl_(6) microcrystal framework,a gradual structure evolution from trigonal to monoclinic phase has been observed,which is accompanied by the redistribution of Li-ions to generate two dimensionally(2D) preferable diffusion pathways through octahedral-tetrahe dral-octahedral sites in In^(3+)-substituted Li_(2)HfCl_(6).Additionally,due to the oxidative stability of Insubstituted Li_(2)HfCl_(6),the bulk-type ASSBs with bare LiCoO_(2) deliver distinguished electrochemical performance. | Kaiyong Tuo Fusheng Yin Fanghui Mi Chunwen Sun | 2023 | Journal of Energy Chemistry2023，，12： | 0 |
