摘要
减少NO_(x)排放是最关键的全球环境问题之一,目前传统的脱硝技术普遍存在反应温度高、催化效率低和成本高等问题,因此光催化氧化、光选择性催化还原等新型光催化脱除NO_(x)技术受到了极大关注。从光催化氧化法和光选择性催化还原法2个方面综述了光催化材料在脱除NO_(x)方面的研究进展,重点介绍了光催化材料的类型、脱除原理和影响脱除效率的因素,并对光催化脱硝材料的今后研究方向进行了展望。
Reducing NO_(x)emission is one of the most critical global environmental problems.At present,the traditional denitrification technology generally has the problems of high reaction temperature,low catalytic efficiency and high cost.Therefore,new photocatalytic NO_(x)removal technologies such as photocatalytic oxidation and photocatalytic selective reduction have attracted great attention.The research progress in NO_(x)removal by photocatalytic materials is reviewed from two aspects including photocatalytic oxidation and photocatalytic selective reduction.The types of photocatalytic materials,the removal principle and the factors affecting the removal efficiency are emphasized.Finally,the prospects for future development of photocatalytic materials used for denitrification are presented.
