loading of metal species in sba-15 for elimination of organic pollutants

Abstract: today, humans are exposed to various dangerous and toxic pollutants throughout their lives. organic compounds such as organic dyes and drugs as water pollutants are necessary to be removed [1]. photocatalysts are widely used in the fields of water purification, pollutant reduction, air purification and degradation of organic contaminants [2]. mesoporous silicate metals are suitable substrate for depositing metal species into their structures [3]. in this study, sba- 15 as a silicate-based mesoporous material were loaded with some transitional metals such as fe2o3 and zno or species including seo2, or its mixed oxide cuo-seo2 with different mass ratios. mesoporous sba-15 was synthesized by hydrothermal method using p123 as structure directing template. the prepared metal –inserted mesoporous materials were studied by xrd, bet, sem, tem, ft-ir and eds [4]. the synthesized photocatalyst with 5-5 w% of cuo-seo2 showed the best photocatalytic efficiency in the degradation of methyl green and methylene blue dyes in an optimal time of 90 minutes under visible light and in the presence of the optimal concentration of h2o2.
