Hosein Golmojdeh, Mohammad A. Zanjanchi and Majid Arvand BiVO4-Silica Composites Containing Cobalt Phthalocyanine Groups: Synthesis, Characterization and Application in Photodegradation of 2,4,6-Trichlorophenol Photochemistry and Photobiology 89
A facile process was developed to produce BiVO4-Silica composites with different silica contents. The composites were modified with sulfonated cobalt phthalocyanine. Both phthalocyanine and BiVO4 are visible-light driven photoactive catalysts. It was observed that presence of silica led to anchorage of phthalocyanine due to surface modification. The sample with nominal 15% silica content showed the best photocatalytic activity in degradation of 2,4,6-trichlorophenol.
