Comparative Study of the Physicochemical Properties and Photocatalytic Activity of Modified McM-41 Synthesized by Direct (One-Step) Incorporation and Impregnation
Abstract:publicado na web em 12/04/2016 MCM-41 structures were synthesized and modified by direct (one-step) incorporation (DI) and wet impregnation (WI) methods. The solids were characterized by XRF, XRD, N 2 adsorption and UV-Vis DR, and catalytically evaluated in the Acid Orange 7 (AO7) degradation under visible light. Significant influence of the presence, dispersion and location of the different Cr species on photoactivity was evident. Both synthesis methods allowed greater dispersion of the photoactive Cr species… Show more
