Amine Functionalized Zeolites: Modification Strategy and Application

Abstract Amination modification of zeolites with various organic or inorganic nitrogen‐containing functional groups can effectively improve their performance. The increasing demand for zeolites in the catalysis and adsorption fields has become the driving force for the development of advanced materials with high catalytic activity and adsorption capacity. After amination modification, the defects of zeolites could be compensated and their applicability could be improved. Amine modified zeolites have a wide range of applications, such as excellent catalyst performance by alkalinity enhancement and high adsorption efficiency for organic and inorganic materials by increasing active sites. Thus, amination modification of zeolite can meet a wider range of needs to promote the practical application of zeolite. However, the amination modification summary of zeolite has not been fully described. This paper summarized the amination modification materials, the amination modification methods and mechanisms, and the application of aminated modified zeolites. It also analyzed existing problems in the current amination modification of zeolites, put forward study directions and targeted suggestions for zeolite amination modification in the future.
