Abstract:
The org an ic contam inan t, m ethy lene b lue(MB) w as deg radated by N, S-codoped T iO2 nano-particles under m ercury lamp or so lar light irrad iation, whose degradation rate w as compared w ith undoped, N-doped, and S-doped T iO2. 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. It was found that when the pH value of me thy lene b lue so lution w as 7 and the ca lc ined tem pe ra ture o f pho toca t a lyst w as 450℃ , N, S-codoped T iO2 owned optima l degrada tion ra te.
