双原子催化剂的制备及在水处理中的应用
Preparation and the Application of Diatomic Catalysts in Water Treatment
摘要
Abstract
[Objective]With the development of society and the improvement of people's environmental awareness,in order to better degrade various pollutants in water,researchers have explored diatomic catalysts(DACs).The preparation and application of DACs in water treatment are discussed in this paper.[Methods]By summarizing the existing literature and focusing on the research frontier of DACs,this review briefly introduces the structure types and characteristics of DACs,systematically analyzes the five main preparation method of DACs(wet chemistry,ball milling,atomic layer deposition,pyrolysis,electrochemical deposition)and their advantages and disadvantages.The application of DACs in photocatalysis,electrocatalysis and Fenton-like catalysis in the treatment of organic pollutants in water is also emphasized.[Results]DACs is a catalyst with two atomically dispersed metal active sites,which is expanded on the basis of the original single atom catalyst(MACs).Based on the synergistic interaction between the active centers of two metal atoms,DACs can effectively reduce the activation energy of the reaction and significantly increase the reaction rate and catalytic activity compared with a single metal active site,which has great potential in water treatment applications.[Conclusion]Based on the above studies,it can be seen that DACs has unparalleled excellent performance in the efficient degradation of pollutants in water,and is a new type of catalyst with great development prospects,which has shown broad development and application prospects in the field of water treatment.At the same time,DACs also has broad application prospects in the fields of energy conversion,environmental protection and chemical synthesis.This paper presents a good outlook on the future opportunities and challenges in the field of DACs.关键词
