Advances in catalysts for synergistic elimination of VOCs and NOx
VOCs and NOx are precursors of PM2.5 and ozone,which can pose a severe threat to both the environment and human health.Catalytic technology is considered a promising multi-pollution treatment for the synergistic elimination of VOCs and NOx,and is expected to achieve reductions in PM2.5 and ozone levels.In recent years,researchers have conducted extensive studies on catalysts for the synergistic removal of VOCs and NOx,and the reaction mechanism of synergistic catalysis has also been studied in-depth.This paper reviews the current research progress on catalysts for the synergistic catalysis of VOCs and NOx.It discusses the latest research on different types of catalysts for the syner-gistic removal of VOCs and NOx,including vanadium-based catalysts,manganese-based catalysts,and molecular sieve catalysts.The influence of the structure and physicochemical properties of catalysts on the activity and reaction pathways have been deeply discussed.Additionally,the reaction mechanism of the synergistic catalytic process and the impact of each component on the catalytic reaction are ex-plored.The article also analyses the possible problems and deficiencies of VOCs and NOx synergistic catalysis in practical applications.Finally,the article provides suggestions for the future development of multi-pollution synergistic catalysts.
