Abstract:
BiVO4-silica composites were prepared and grafted with sulfonated cobalt phthalocyanine. The structural and chemical properties including crystalline phase, specific surface area, UV-Visible diffuse reflectance behavior, morphology and photocatalytic activity were investigated. Depending on the silica content and subsequently amounts of loaded phthalocyanine, various catalytic activities were observed. The sample containing nominal 15% silica and grafted with phthalocyanine showed less aggregated form of this organic dye, smaller and nanometric particles, and higher photocatalytic activity in degradation of 2,4,6-trichlorophenol.
