Abstract

Grinding (solvent-free) method was used as a superior technique to prepare mesoporous PHOTOCATALYSTs of ZnO, ZnS, ZnO / ZnS, CdO, CdS and CdO / CdS-SBA-15. In this technique, the nitrate, acetate and chloride salts of ZINC and/or CADMIUM were grinded with as-synthesized SBA-15 as a mesoporous material. The controllable sulfurationis was used to prepare ZnS, ZnO/ZnS, CdS and CdO/CdS-SBA-15 at temperature of 80oC. The advantages of grinding technique were: i) the elimination of solvent and thus decrease of expense and ii) the complete incorporation of metal salts in the nanochannel of mesoporous material in a short time. X-ray powder diffraction, N2 adsorption-desorption and FT-IR spectroscopy were used to characterize the prepared materials. The highly dispersed semiconductors in SBA-15 demonstrate an active photodegradation of CONGO RED in aqueous solution. The nanocomposites of ZnO/ZnS and CdO/CdS in channels of SBA-15 showed the highest photocatalytic activity. The photocatalytic activity of ZnO-, ZnS- and ZnO/ZnS-SBA-15 were also dependent on the salt precursor of ZINC. The prepared composite PHOTOCATALYSTs of ZINC/SBA-15, by using ZnCl2 as salt precursor, indicated the higher activity.
