首发时间：2023-12-22
摘要：近年来，原子分散的过渡金属单原子材料与含金属纳米颗粒的多相催化剂相比，具有最大的原子利用率和有效的活性位点。已成为电催化领域最受欢迎的研究热点之一。已有大量研究报道其在电催化氧还原（orr）、氧析出（oer）、二氧化碳还原（co2rr）和光催化领域均表现出优异的催化活性。目前，关于单原子催化剂的研究主要集中于高活性和优异稳定性的单原子催化剂的可控构筑以及深入了解单原子的催化活性机制。本文综述了单原子催化剂的常见类型及其在氧还原领域的研究进展。

the progress of single-atom catalysts and its study in electrocatalytic oxygen reduction field
abstract：in recent years, atomically dispersed transition metal single-atom materials have maximum atom utilization and effective active sites compared with multiphase catalysts containing metal nanoparticles. it has become one of the most popular research hotspots in electrocatalysis. numerous studies have been reported that they exhibit excellent catalytic activities in electrocatalytic oxygen reduction (orr), oxygen precipitation (oer), carbon dioxide reduction (co2rr) and photocatalysis. currently, studies on single-atom catalysts are mainly focused on the controlled construction of highly active and excellent stable single-atom catalysts as well as a deeper understanding of the mechanism of catalytic activity of single atoms. this paper reviews the common types of single-atom catalysts and their research progress in the field of oxygen reduction.
