从结构到性能，合理的结构设计导致高性能电化学性能使金属有机框架（MOF）在能量转换方面取得了巨大成就。由于 Co(II) 具有多个价态并且特别丰富，因此 CoMOF 已成为整体水分解中电催化剂的潜在材料。事实上，CoMOFs/碳基杂化材料（Co/CHMs）表现出各种结构、奇妙的电化学能力和协同效应，克服了CoMOFs和单一结构碳材料的相对绝缘性。基于 CoMOFs 的材料和碳材料形成独特界面的协同效应可以增加比表面积并加速电子转移速率，从而增强整体水分解。在本综述中，总结了各种 Co/CHM（碳 = GO/RGO、CNT 和炭黑）。讨论了Co/CHMs的协同效应与整体水分解活性之间的关系。最后，这篇综述可以为Co/CHMs作为电催化剂在全水分解领域提供一定程度的参考，并为未来的能源材料提供一些有益的评论。

Compositional Engineering of Co(II)MOF/Carbon-Based Overall Water Splitting Electrocatalysts: From Synergistic Effects to Structure–Activity Relationships

Ranging from structure to property, the design of reasonable structures leading to high-performance electrochemical properties has enabled metal–organic frameworks (MOFs) to have great achievement in energy conversion. Since Co(II) has multiple valence states and is especially abundant, CoMOFs have emerged as latent materials of electrocatalysts in overall water splitting. In fact, CoMOFs/carbon-based hybrid materials (Co/CHMs) exhibit all kinds of architectures, marvelous electrochemical capabilities, and synergistic effects, overcoming the relative insulation of CoMOFs and single structure carbon materials. The synergistic effect of CoMOFs-based materials and carbon materials forming a unique interface can increase the specific surface area and accelerate electron transfer rates, resulting in enhanced overall water splitting. In terms of this review, the various Co/CHMs (carbon = GO/RGO, CNT, and carbon black) are summarized. The relationship between the synergistic effect of Co/CHMs and the activity of overall water splitting is discussed. Finally, this review can supply a certain degree of reference for Co/CHMs as electrocatalysts in the field of overall water splitting and a number of helpful comments for prospective energy materials.
