Electrocatalysis is the most important electrode reactions for many energy storage and conversion devices, which are considered a key part of the resolution of the energy crisis. Toward this end, design of efficient electrocatalysts is of critical significance. While extensive research has been extended to develop excellent electrocatalysts, the fundamental understanding of the relationship between the electronic and structural properties of electrocatalysts and the catalytic activity must remain a priority. In this review, the activity modulation of electrocatalysts by charge transfer effects, including intramolecular and intermolecular charge transfer, is systematically introduced. With suitable charge transfer modification, such as heteroatom doping, defect engineering, molecule functionalization, and heterojunctions, the electrocatalytic activity of carbon‐based electrocatalysts can be significantly boosted. The manipulation of the electronic structure of carbon‐based materials by charge transfer may serve as a fundamental mechanism for performance enhancement. After establishing an understanding of the relationship between catalytic activity and charge transfer, the opportunities and challenges for the design of electrocatalyst with charge transfer effects are discussed.

碳基电催化剂的电荷转移调节活性

电催化是许多能量存储和转换设备中最重要的电极反应,被认为是解决能源危机的关键部分。为此,有效的电催化剂的设计具有至关重要的意义。尽管已经进行了广泛的研究以开发优异的电催化剂,但是对电催化剂的电子和结构性质与催化活性之间的关系的基本理解仍然是优先事项。在这篇综述中,系统地介绍了通过电荷转移效应(包括分子内和分子间电荷转移)对电催化剂的活性调节。通过适当的电荷转移修饰,例如杂原子掺杂,缺陷工程,分子功能化和异质结,碳基电催化剂的电催化活性可以大大提高。通过电荷转移对碳基材料的电子结构进行操纵可能是提高性能的基本机制。在了解了催化活性和电荷转移之间的关系之后,讨论了具有电荷转移效应的电催化剂设计的机遇和挑战。
