Degradation of Phthalocyanine by a Core-Shell TiO2 Photocatalyst:Effect of Iron Dopping on Band Gap

In this research, initially, the sol-gel method was employed to produce γ-alumina and tio2 catalystswith core-shell structure. iron (iii) was used as a dopant. the newlyproduced core-shells werefe/tio2// fe/ γ-al2o3 (ftfa). sulfonated cobalt phthalocyanine was used as a dye pollutant inmerox process. by doping fe in tio2 catalyst, the efficiency of photocatalytic activity inphotodegradation of sulfonated cobalt phthalocyanine was increased. photocatalytic activity offe/tio2// fe/ γ-al2o3 in uv irradiation was investigated and complete degradation of sulfonatedcobalt phthalocyanine was confirmed via uv-vis spectrophotometry and total organic carbonanalysis. structure, morphology, and specification of new core-shell composites of ftfa werestudied using several spectroscopic techniques. the efficiency of the ftfa catalyst is very good inalkaline media and close to the tio2 catalyst performance in acidic media. the completedestruction process was investigated with toc and the synthesized catalyst degraded 5 ppm ofsolution polluted by scp in a maximum of 30 min.
