“…Existing studies have shown that doping of non-metallic sites at different positions and in different quantities alters the electronic structure of the metal active site, thereby affecting the atomic charge distribution in the neighboring metal centers. [30] At the same time, these changes will indirectly affect the electron distribution and spin of the metal center through long-range interactions, thus enhancing the catalytic performance. This has important implications for the precise design and characterization of single-atom catalysts (see Figure 10c).…”

Single‐atom catalysis involves loading the active metal onto the carrier's surface as a single‐atom. This atom is primarily bonded to the carrier surface through hetero‐atom bonding. It is important to note that the coordination environment of the metal atoms may not be the same when each dispersed active metal atom has an identical coordination environment on the carrier's surface. The utilization of single‐atom catalysts (SACs) doesn't strictly imply that a solitary metal atom with zero valency functions as the active core. Singular atoms can also engage in distant interactions with other atoms or clusters of atoms on the substrate, like electron transfer, and frequently demonstrate specific charges. The main reason for the high activity of the catalyst is the remote (i.e., long‐range) interaction of the active atom with the surrounding coordination atoms. For this reason, the study of the mechanism of long‐range interactions between multiple single‐atom sites and between single‐atom sites and atomic cluster sites has become an important and urgent task in the design and regulation of single‐atom catalyst performance.

Carbon neutrality is an important goal for humanity . As an eco‐friendly technology, electrocatalytic clean energy conversion technology has emerged in the 21st century. Currently, metal‐organic framework (MOF)‐based electrocatalysis, including oxygen reduction reaction (ORR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), hydrogen oxidation reaction (HOR), carbon dioxide reduction reaction (CO2RR), nitrogen reduction reaction (NRR), are the mainstream energy catalytic reactions, which are driven by electrocatalysis. In this paper, the current advanced characterizations for the analyses of MOF‐based electrocatalytic energy reactions have been described in details, such as density function theory (DFT), machine learning, operando/in situ characterization, which provide in‐depth analyses of the reaction mechanisms related to the above reactions reported in the past years. The practical applications that have been developed for some of the responses that are of application values, such as fuel cells, metal‐air batteries, and water splitting have also been demonstrated. This paper aims to maximize the potential of MOF‐based electrocatalysts in the field of energy catalysis, and to shed light on the development of current intense energy situations.
