      报告摘要：

Renewable energy technologies, such as water electrolyzers, fuel cells, and metal–air batteries, are being vigorously pursued in the current era of heightened focus on sustainability. As the cornerstone of these technologies, the electrocatalyst must meet stringent requirements for low cost and high performance, especially when considering large-scale applications. Atomic-level electrocatalyst design has, therefore, attracted extensive interests due to its merits of much more sustainable ways in increasing atom utilization efficiency and maximizing the activity per metal atom. 'Single-atom catalysis', strictly adhering to the principles of electrocatalyst design atom-by-atom, has become the most popularized concepts in electrocatalysis. In relevant studies, metal–nitrogen–carbon (M–N–C) materials are the most representative electrocatalyst system, predominantly employed for the oxygen reduction reaction (ORR) in fuel cells and metal–air batteries. Due to their structural similarity to the oxygen-binding site in cytochrome c oxidase, single-atom MNx, especially those centered around iron, offer substantial ORR activity. Herein, we draw inspiration from this structural enzymology, and design a series of M–N–C electrocatalysts for the ORR. A thorough and unified mechanistic picture that we expect to obtain from our studies will improve the existing theory of single-atom catalysis and provide atomistic insight into the reaction mechanism of electrocatalysis.
