Mn基催化剂在VOCs和NOx热催化净化中的研究进展
Research progress of Mn-based catalysts in the thermal catalytic purification of VOCs and NOx
摘要
Abstract
The synergistic co-control of volatile organic compounds(VOCs)and nitrogen oxides(NOx)plays a crucial role in environmental protection,serving as a key step in reducing PM2.5 concentrations and achieving the "Air Quality Continuous Improvement Action Plan".This aligns with the eco-civilization philosophy of green and sustainable development in the new era.In recent years,the development of bifunctional catalysts capable of simultaneously removing VOCs and NOx has attracted significant attention.Such catalysts must integrate the functions of catalytic oxidation of VOCs and selective catalytic reduction(SCR)of NOx,often employing binary or multi-metal catalyst designs in their development.Mn-based catalysts have emerged as a research hotspot in the field of thermal catalytic purification of VOCs and NOx due to their low cost,rich valence states,and ability to form redox cycles with various metals,demonstrating broad application prospects.This review summarizes the latest research progress in Mn-based catalysts for the separate and synergistic thermal catalytic purification of VOCs and NOx,introducing their classifications,common preparation methods,and advancements in poisoning resistance for VOC and NOx thermal catalytic purification.Finally,the discussion categorizes scenarios in synergistic thermal catalytic treatment technologies for VOCs and NOx based on whether ammonia is added as a reducing agent,while also providing an outlook on future development directions for this technology.The aim is to offer guidance for constructing novel,highly efficient,multi-pollutant synergistic catalytic purification systems.关键词
