Abstract
En 中文
Metal-organic frameworks (MOFs) have garnered significant attention in electrocatalysis for their high porosity, expansive surface area, presence of unsaturated metal coordination sites, and structural diversity. Yet pristine MOFs are limited in practical applications due to their poor electrical conductivity, low stability, and insufficient active sites, while traditional MOF-derived calcination methods often damage the native structure and reduce active site utilization. Defect engineering has emerged as a research frontier in MOF modification, representing an effective strategy to optimize the electronic structure and conductivity, while increasing the density of active sites within pristine MOFs. Specifically, the deliberate introduction of targeted defects in MOFs serves as a crucial strategy to boost their performance across various electrocatalytic applications. This review primarily focuses on recent advances in defective MOFs for electrocatalysis, including the regulation of defects on electrocatalytic performance and their direct applications in energy-related electrocatalysis. By summarizing the advancements in this area, the review seeks to elucidate the relationship between defect characteristics and electrocatalytic performance. Ultimately, it aspires to offer theoretical insights and research avenues for the rational design of high-performance defective MOF electrocatalysts, fostering their progress in advanced energy technologies.
