微波技术在脱硝催化剂制备及NH3-SCR中的应用进展OA

Nitrogen oxides(NOx),as one of the major air pollutants,have always been a research hotspot in the field of environmental catalysis.Selective catalytic reduction(SCR)technology is currently one of the most effective denitrification methods,and the performance of the catalyst directly determines the application effect of SCR technology.Microwave technology,as a highly efficient and energy-saving preparation technology,shows strong application prospects in the preparation of denitrification catalysts due to its unique advantages such as uniform heating,promotion of high dispersion and small particle formation of active components,regulation of catalyst microstructure,and green environmental protection.This paper systematically reviews the application progress of the microwave method in the preparation of denitration catalysts,focuses on discussing the effects of the microwave method on the structure and performance of catalysts as well as their action mechanisms,summarizes the performance characteristics of various microwave-assisted prepared denitration catalysts(including metal oxides,molecular sieves,metal-organic frameworks,and carbon materials),and prospects the development trends and challenges of the microwave method in the preparation of denitration catalysts.
