无机含氮化合物的光催化降解

Photocatalytic Degradation of Inorganic Nitrogenous Compounds

综述了光催化技术在无机含氮化合物方面的应用．从两方面阐述了无机含氮化合物（ＮＯｘ、ＮＯ３－、ＮＯ２－）光催化降解的最新进展，以及增加光催化降解效率的方法（如：对二氧化钛光催化剂进行修饰；研制新型光催化剂；研制新型光反应器；研究光催化降解无机含氮化合物的反应机理）．通过采取各种措施，可使ＮＯｘ的转化率达到 ６０％，ｎ、ＮＯ３－的转化率达３２％，且其中有５０％的转化为Ｎ２·

A review over a lot of scientific literatures summarizes the application of photocatalytic technique in inorganic nitrogenous compounds, and elaborates from the fwo respects the recent research progress of photocatalytic degradation of inorganic nitrogenous compounds (NOx, NO3-, NO2-) and the methods of increasing photocatalytic degradation efficiency (such as the modification of TiO2 photocatalysts, the development of new photocatalysts and new photoreactors, the reaction mechanism of photocatalysis degradation of inorganic nitrogenous compounds). This paper also infroduces the measures of making the conversion rate of NOx up to 60%, NOT to 32%, and evenmaking 50% NOx turn to N2.
