摘要: Mesoporous silica (SBA-15) and iron oxide incorporated (Fe2O3-SBA-15) were synthesized by co-operative self-assembly technique. Samples characterized using nitrogen adsorption–desorption isotherm, electron microscopic spectroscopic techniques. The results confirm the uniform distribution of pores, presence metal oxides in pores as well surface mesoporous wall oxidation state Fe2O3-SBA-15. photocatalytic degradation methylene blue (MB), sulphorhodamine B (SR-B) methyl orange (MO) Fe2O3-SBA-15 was investigated. It observed that degraded 98 % MB, 96 SR-B 99 MO within 3 h after exposure to sunlight. SBA-15 does not exhibit any effect. These demonstrate potential for environmental pollution control.
