摘要
挥发性有机物(VOCs)是一类重要的空气污染物。催化氧化技术可以将VOCs转化为无毒的CO_2和H_2O,是有效的治理方式之一。针对传统的热催化氧化技术的高能耗和光催化净化VOCs技术的低效率问题,光催化耦合强化热催化的光热协同催化净化VOCs技术近些年来受到广泛关注,并表现出比传统热催化或光催化净化技术更优异的净化性能。总结了近年国内外研究者在光热催化净化VOCs领域所取得的主要研究进展,重点讨论了光热协同作用机制的认知和光热协同催化材料的设计理念,包括贵金属型和金属氧化物型光热协同催化材料,并对光热协同催化净化技术的未来发展方向进行了展望。
Volatile organic compounds(VOCs)are an important class of air pollutants.Catalytic oxidationtechnology can convert VOCs into non-toxic CO2and H2O,which is one of the effective treatment methods.Inconsideration with the high energy consumption of the traditional thermal catalysis and the low efficiency of thephotocatalysis during the purification of VOCs,the coupling of photo catalysis and thermal catalysis for VOCspurification has received intense attention.The superior VOCs degradation performance by photo-thermalsynergistic catalysis over the single thermal catalytic or photo catalytic process has been demonstrated.This workreviews the latest progress in the field of catalytic VOCs oxidation by photo-thermal synergistic catalysis with aspecial attention to the understanding of the synergetic mechanism and design of photo-thermal catalytic materials,including noble metal based and metal oxides based catalysts.Finally,future perspectives of photo-thermal catalytictechnology for environmental application are provided.
