H3PW12O40/organobentonite was prepared from H3PW12O40 and organobentonite using reflux-adsorption. In view of the photo-Fenton catalytic performance, the effects of relfux-adsorption time, relfux-adsorption temperature, calcination temperature and calcination time on the catalytic activity of H3PW12O40/organobentonite were investigated. The preferable process conditions for preparation of H3PW12O40/organobentonite were obtained as following: reflux-adsorption time 4 h, reflux-adsorption temperature 80℃, calcination temperature 200℃ and calcination time 2 h. H3PW12O40/organobentonite had good catalytic stability. Catalyst characterization showed H3PW12O40 was successfully immobilized on organobentonite, and H3PW12O40/organobentonite was a layered composite material with the porous structure. The immobilization mechanism of H3PW12O40 was chemical grafting.
