Transition metal dichalcogenides (TMDCs) hold great promise for electrochemical energy conversion technologies in view of their unique structural features associated with the layered structure and ultrathin thickness. Because the inert basal plane accounts for the majority of a TMDC's bulk, activation of the basal plane sites is necessary to fully exploit the intrinsic potential of TMDCs. Here, recent advances on TMDCs-based hybrids/composites with greatly enhanced electrochemical activity are reviewed. After a summary of the synthesis of TMDCs with different sizes and morphologies, comprehensive in-plane activation strategies are described in detail, mainly including in-plane-modification-induced phase transformation, surface-layer modulation, and interlayer modification/coupling. Simultaneously, the underlying mechanisms for improved electrochemical activities are highlighted. Finally, the strategic evaluation on further research directions of TMDCs in-plane activation is featured. This work would shed some light on future design trends of TMDCs-based functional materials for electrochemical energy-related applications.

用于电化学能量转换的过渡金属二硫属化物的新进展

过渡金属二硫属化物 (TMDC) 具有与层状结构和超薄厚度相关的独特结构特征，因此在电化学能量转换技术方面具有广阔的前景。因为惰性基面占 TMDC 的大部分，基面位点的激活对于充分利用 TMDC 的内在潜力是必要的。在此，综述了电化学活性大大增强的基于 TMDC 的杂化物/复合材料的最新进展。在总结了不同尺寸和形态的 TMDC 的合成后，详细描述了全面的面内激活策略，主要包括面内改性诱导相变、表面层调制和层间改性/耦合。同时，强调了改善电化学活性的潜在机制。最后，对TMDCs面内激活的进一步研究方向进行了战略评估。这项工作将为基于 TMDC 的功能材料在电化学能源相关应用中的未来设计趋势提供一些启示。
