Supported dual-atom catalysts: Preparation, characterization, and potential applications

Publication date: May 2020Source: Chinese Journal of Catalysis, Volume 41, Issue 5Author(s): Jing Zhang, Qiu-an Huang, Juan Wang, Jing Wang, Jiujun Zhang, Yufeng ZhaoDeveloping sustainable and clean electrochemical energy conversion technologies is a crucial step in addressing the challenges of energy shortage and environmental pollution. Exploring and developing new electrocatalysts with excellent performance and low cost will facilitate the commercial use of these energy conversion technologies. Recently, dual-atom catalysts (DACs) have attracted considerable research interest since they exhibit higher metal atom loading and more flexible active sites compared to single-atom catalysts (SACs). In this paper, the latest preparation methods and characterization techniques of DACs are systematically reviewed. The advantages of homonuclear and heteronuclear DACs and the catalytic mechanism and identification technologies between the two DACs are highlighted. The current applications of DACs in the field of electrocatalysis are summarized. The development opportunities and challenges of DACs in the future are prospected. The ultimate goal is to provide new ideas for the preparation of new catalysts with excellent properties by customizing diatomic catalysts for electrochemical applications.Graphical AbstractDual-atom catalysts, for homonuclear and heteronuclear dual-atom catalysts, including their synthesis, characterization, and the application of electrocatalytic systems and el...
