The precursor was injected into the zinc nitrate hexahydrate (Zn(NO3)2˙6H2O) and stay overnight. The as-prepared spheres was calcined at 550℃ for 3 hrs to remove the polymer parts.
The sulfur and nitrogen co-doped TiO2 micro/nano- spheres were characterized by thermogravimetric analyzer, Scanning electron micros-copy, X-ray diffraction, ultraviolet/visible absorption spectroscopy, N2 adsorption/desorption. The photocatalytic activities of sulfur and nitro-gen co-doped TiO2 microspheres under UV light were estimated by measuring the degradation rate of Rhodamine B in aqueous solution.
These results indicated that the energy gap of porous sulfur and ni-trogen co-doped titanium dioxide is 1.85 eV. The sulfur and nitrogen co-doped titanium dioxide showed the degradation rate is 90%.
