摘要
非层状过渡金属碳化物(NL-TMCs)具有多样化的形貌结构和可调控的化学计量比,从而表现出高比容量、高导电性和良好的稳定性等优异的电/催化性能。因此,本文对NL-TMCs在储能与转换领域的最新进展进行了总结。首先阐述了NL-TMCs的可控制备策略,其中包括碳热还原法、化学气相沉积法、模板辅助法、水热/溶剂热法。其次,探讨了NL-TMCs在锂离子电池、锂硫电池、全水解等能源储存与转换领域中应用,并对其未来的发展方向进行了展望,为合理地设计和构建NL-TMCs以供实际应用提供了理论基础。
Non-layered transition metal carbides(NL-TMCs)have diverse morphologies and structures,and tunable stoichiomet-ric ratios,giving them many intriguing electrical/catalytic properties such as high gravimetric capacities,high conductivity and excel-lent stability.The latest progress in the use of NL-TMCs for energy conversion and storage applications is reviewed.Several routes to synthesize NL-TMCs are described,including carbothermal reduction,chemical vapor deposition,a template-assisted method and a hydro/solvothermal method.Their electrochemical performance in lithium-ion batteries,lithium-sulfur batteries and catalytic water splitting are presented.Current challenges for the rational design and fabrication of NL-TMCs for practical applications are dis-cussed and future research suggestions are made.
