Carbon materials-supported metal catalysts are of great significance to the renewable energy conversion. More than a support to immobilize metal nanoparticles and improve atomic usage, the carbon materials can also impact the catalysis performance in a way of engineering the electronic structure of active metal components. The modulation of such an electronic metal–support interaction (EMSI) for designing efficient catalysts has been a hotspot in recent years. Benefiting from the development of advanced characterization techniques and theoretical simulations, one can shed light on the key points regarding EMSI and construct the relationship between EMSI and catalysis performance. In this Review, we summarize the recent work concerning the electronic interaction between carbon supports and metals, and discuss the underlying factors, including the nature of metal, metal morphology, metal particle size, carbon structure, heteroatom doping, carbon coating, and interfacial binding. The relationship between EMSI and the catalytic performance, by taking hydrogen/oxygen electrocatalysis for examples, is highlighted. These summaries would deepen the understanding of EMSI and favor the progress of carbon-supported metal catalysts.

设计用于氧/氢电催化的金属和碳载体之间的电子相互作用

碳材料负载的金属催化剂对可再生能源转化具有重要意义。碳材料不仅是固定金属纳米颗粒和提高原子利用率的载体，还可以通过设计活性金属成分的电子结构来影响催化性能。近年来，用于设计高效催化剂的这种电子金属-载体相互作用（EMSI）的调节一直是一个热点。受益于先进表征技术和理论模拟的发展，人们可以阐明 EMSI 的关键点，并构建 EMSI 与催化性能之间的关系。在这篇综述中，我们总结了最近关于碳载体和金属之间电子相互作用的工作，并讨论了潜在的因素，包括金属的性质、金属形态、金属粒径、碳结构、杂原子掺杂、碳涂层和界面结合。以氢/氧电催化为例，突出了EMSI与催化性能之间的关系。这些总结将加深对 EMSI 的理解，并有利于碳负载金属催化剂的进展。
