摘要:
用自制N、S共掺杂的TiO2纳米粉体降解亚甲基兰溶液,同未掺杂、单掺N或单掺S的TiO2纳米粉体做了比较,系统地研究了影响TiO2降解亚甲基兰溶液的因素.结果显示,无论是太阳光还是紫外光照射下,N、S共掺杂的TiO2纳米粉体具有比其它三种光催化剂更好的催化效果,并且发现在煅烧温度为450℃、亚甲基兰溶液的pH值为中性条件下,N、S共掺杂的TiO2纳米粉体降解效果达到最佳.

As a result, N, S-codoped T iO2 photocata lyst show edm arked synerg ic effec t and better photocata ly tic activ ity than o ther three k inds o f pho tocata lyst. And the photoca talytic ac tiv ity o fN, S-codoped T iO2 nano-particlew as eva luated sys tem atically inc luding the different pH va lues o fm ethylene b lue so lution and the d iffe rent ca lc ined tem pe ra ture o f pho to ca talyst.
