| 1 | Issues and solutions toward zinc anode in aqueous zinc-ion batteries: A mini review显示文摘Aqueous zinc-ion batteries(ZIBs)have been intensively investigated as potential energy storage devices on account of their low cost,environmental benignity,and intrinsically safe merits.With the exploitation of highperformance cathode materials,electrolyte systems,and in-depth mechanism investigation,the electrochemical performances of ZIBs have been greatly enhanced.However,there are still some challenges that need to be overcome before its commercialization.Among them,the obstinate dendrites,corrosion,and hydrogen evolution reaction(HER)on Zn anodes are critical issues that severely limit the practical applications of ZIBs.To address these issues,various strategies have been proposed,and tremendous progress has been achieved in the past few years.In this article,we analyze the origins and effects of the dendrites,corrosion,and HER on Zn anodes in neutral and mildly acid aqueous solutions at first.And then,a scientific understanding of the fundamental design principles and strategies to suppress these problems are emphasized.Apart from these,this article also puts forward some requirements for the practical applications of Zn anodes as well as several cost-effectivemodifying strategies.Finally,perspectives on the future development of Zn anodes in aqueous solutions are also briefly anticipated.This article provides pertinent insights into the challenges on anodes for the development of highperformance ZIBs,which will greatly contribute to their practical applications. | Chunlin Xie Yihu Li Qi Wang Dan Sun Yougen Tang Haiyan Wang | 2020 | Carbon Energy2020，2，4： | 15 |
| 2 | 水系锌离子电池金属负极的挑战与优化策略显示文摘水系锌离子电池(ZIBs)由于其安全性好,成本低和环境友好等特点,被认为是非常有潜力的储能系统,得到了广泛的研究。目前尽管在高性能正极材料的研究方面取得了快速进展,但关于锌负极的研究还有不足。为了解决锌负极的固有缺点,在提高锌负极性能和负极保护方面提出了很多策略。本文通过对相关文献的探讨,总结了库仑效率(CE)低和循环性能差是锌负极现阶段面临的挑战,进一步分析了这主要是由于锌负极枝晶生长和腐蚀现象引起。通过回顾近期锌负极自身设计和电解液优化改变锌负极界面特性的研究,分别从锌负极合金化处理,锌负极表面结构改造,锌负极界面保护,电解液锌盐对比,电解液添加剂,凝胶电解液共六个方面详细分析并对比了改善锌负极性能的具体方式。最后概括了锌离子电池的研究必要性,展望了未来稳定锌负极界面的策略。 | 王心怡 李维杰 韩朝 刘化鹍 窦世学 | 2022 | 储能科学与技术2022，11，4： | 6 |
| 3 | Self-catalyzed formation of strongly interconnected multiphase molybdenum-based composites for efficient hydrogen evolution显示文摘Molybdenum carbide(MoxC)with variable phase structure possesses flexible hydrogen-binding energy(HBE),which is a promising hydrogen evolution reaction(HER)catalyst.Herein,a hybrid multiphase MoxC freestanding film coupled with Co3Mo(CM/MoxC@NC)is synthesized through the electrospinning method supplemented by the heteroatom incorporation.CM/MoxC@NC surpasses its pure phase counterparts and exhibits remarkable catalytic activity at 114mV to deliver a current density of 10mA cm^(−2) in acid,which is among the first-rate level performance reported for MoxC-based catalysts.The subsequent ex situ and in situ characterizations reveal a phase transition mechanism based on self-catalysis that CoOx depletes the coordinated C ofα-MoC via the interaction,which realizes the assembly of weak HBEα-MoC and strong HBEβ-Mo2C,and the enhanced utilization of active materials as well.The multiple structures with optimal HBE are in favor of the stepwise reactions of HER,as the study of the correlation between HBE and phase structure revealed.This study discloses the underlying phase transition mechanism and highlights the HBE–structure relationship that should be considered for catalyst design. | Jiani Chen Haijuan Zhang Jie Yu Daqin Guan Sixuan She Wei Zhou Zongping Shao | 2022 | Carbon Energy2022，4，1： | 2 |
| 4 | Advances of the functionalized carbon nitrides for electrocatalysis显示文摘Over the past few decades,the design and development of carbon materials have occurred at a rapid pace.In particular,these porous graphene-like carbon nitride materials have received considerable attention due to their superior structures and performances in the energy transformation field.In this review,nitrogenated holey two-dimensional graphene and polymeric carbon nitride will be discussed in depth.The structural properties,synthetic methods,and applications including electrocatalytic reactions,such as hydrogen evolution reaction,oxygen reduction reaction,oxygen evolution reaction,and nitrogen reduction reaction,will be presented in detail.Finally,we will present the outlooks on the current obstacles to the development of carbon nitride materials.This comprehensive understanding will help guide and motivate researchers to develop and modify carbon nitride materials with better properties in the future. | Qianqian Fan Jianan Su Tao Sun Zenghui Bi Huaisheng Wang Shusheng Zhang Qingju Liu Longzhou Zhang Guangzhi Hu | 2022 | Carbon Energy2022，4，2： | 0 |
| 5 | Visualization of an Accelerated Electrochemical Reaction under an Enhanced Electric Field显示文摘Locally enhanced electric fields produced by high-curvature structures have been reported to boost the charge transport process and improve the relevant catalytic activity.However,no visual evidence has been achieved to support this new electrochemical mechanism.Here,accelerated electrochemiluminescence(ECL)reactions emitting light are visualized for the first time at the heterogeneous interfaces between microbowls and the supporting electrode surface.The simulation result shows that the electric intensity at the interface with a high curvature is 40-fold higher than that at the planar surface.Consequently,local high electric fields concentrate reactive species to the heterogeneous interfaces and efficiently promote the charge transport reactions,which directly leads to the enhancement of ECL emission surrounding the microbowls.Additionally,the potential to induce visual ECL from a ruthenium complex drops to 0.9 V,which further illustrates the promotion of an electrochemical reaction with the aid of an enhanced electric field.This important visualization of electric field boosted electrochemical reactions helps to establish the proposed electron transfer mechanism and provide an alternative strategy to improve electrocatalytic efficiency. | Chen Cui Rong Jin Dechen Jiang Jianrong Zhang Junjie Zhu | 2021 | Research2021，，1： | 0 |
