Abstract
The effect of microbe combination with TiO2 on photocatalytic degradation of Rhodamine B was investigated. The self-assembled TiO2 spheres were synthesized by the solvothermal method for preparation of hybrid TiO2/Paint Sludge Extracted Microbe (PSEM) composite. The structure of as-synthesized TiO2 was analyzed by the powder X-ray diffraction method, and phase purity was verified with Raman analysis. Spherical morphology and self-assembled nature of TiO2 was confirmed by field emission scanning electron microscopy (FE-SEM). PSEM extracted from Paint sludge and was used to synthesize TiO2/PSEM hybrid composite. The dispersion of TiO2 self-assembled spheres on the walls of PSEM was confirmed with FE-SEM micrographs. TiO2/PSEM composite (94%) showed enhanced photocatalytic dye degradation when compared with as-synthesized TiO2 (85%).
