气态氨（NH3）对人体健康和环境都有害。选择性催化氧化NH3（NH3- sco）生成n2和H2O是一种很有前途的消除气态NH3的方法。考虑到催化剂的性能和成本，银基催化剂被认为是最有潜力的候选催化剂。本文综述了近几十年来银基催化剂在NH3-SCO领域的研究进展。重点介绍了银基催化剂的组成和理化性质对NH3-SCO性能的影响，并对催化剂的催化反应机理和构效关系进行了综述。最后，提出了NH3-SCO中高性能银基催化剂的发展方向和设计策略。
Gaseous ammonia (NH3) is harmful to both human health and the environment. Selective catalytic oxidation of NH3(NH3-SCO) to N2and H2O is a highly promising method for the elimination of gaseous NH3. Considering catalyst performance and cost, Ag-based catalysts are regarded as the candidates with the most potential. In this paper, we summarize the research advances in the field of NH3-SCO by Ag-based catalysts, which have aroused extensive interests in the past decades. We highlight the influence of the catalyst composition and physicochemical properties of Ag-based catalysts on NH3-SCO performance, and give an overview of the catalytic reaction mechanism and the structure-activity relationship of catalysts. Finally, directions and design strategies for high-performance Ag based catalysts in NH3-SCO are also provided.
