摘　　要：用二乙胺法合成的二氯二茂钛的吸收光谱有一定程度的红移,在可见光区有很强的吸收,用活性炭作载体,浸渍二氯二茂钛溶液,在模拟自然光蓝光照射下,光催转化降解氮氧化物,催化活性高,最终氧化产物可用水洗除去,没有任何离子掺杂的情况下,NO的降解率为52.8%,实现了氮氧化物的可见光有效催化降解,条件更为温和。The absorption spectrum of dichlorotitanocene synthesized by diethylamine method has a certain degree of red shift,and it has strong absorption in the visible region.It is impregnated with activated carbon as a carrier and impregnated with dichlorotitanium dichloride solution.Under irradiation,photocatalytic degradation of nitrogen oxides has high catalytic activity.The final oxidation product can be removed by water washing.Without any ion doping,the degradation rate of NO is 52.8%,and the visible light effective catalytic degradation of nitrogen oxides is achieved.The conditions are more moderate.
