Abstract:
Background and Objective: Dispersion of silver compounds onto appropriate support is an adequate procedure for fabricating active photocatalysts for degradation of environmental pollutants. The current study investigated the dispersion of AG3PO4 as potential photocatalyst onto MCM-41 as a mesoporous support. Materials and Methods: The disodium hydrogen phosphate was found to be an appropriate source of phosphate for the synthesis of AG3PO4/MCM-41. Two different procedures of post-synthesis and during-synthesis methods were used for preparation of the photocatalysts. Accurate structural and analytical methods were used for characterization of the prepared photocatalysts. Results: The XRD results revealed that all the materials showed a body-centered cubic crystal structure. Maximum Elimination of methylene blue dye was found within 15 min, in slightly acidic media in the presence of photocatalyst. Pseudo first order was the best fitted model for this study. Conclusion: The post-synthesized AG3PO4/MCM-41 showed the highest capability for elimination of methylene blue and 2,4-dichlorophenol. Part of this capability for elimination of methylene blue is due to its adsorption onto the photocatalyst.
