ABSTRACT
A visible light active photodegration catalyst was prepared by doping MoO(3) into MgF(2) matrix. The addition of SO(4)(2-) into MoO(x)/MgF(2) could improve the catalytic activity greatly and an acetone conversion of 96.1% under visible light was obtained on the SO(4)(2-)/5%MoO(x)/MgF(2) (SMM) catalyst. By BET, XRD, Raman, FT-IR, XPS, UV-vis technology the specific area, structure and photoadsorption ability of the catalysts were characterized. The high photocatlaytic activity of the SMM catalyst is attributed to its large specific area, the high dispersal of MoO(3) domains in MgF(2) and the inhibiting effect of MgF(2) matrix on the electron-hole pair recombination.
