C, S & N-Doped TiO2 Photocatalyst Prepared by the Reverse-Microemulsion Method
After TiO2/SPAN (Sulfonated Polyaniline) complex prepared by the reverse-microemulsion method was calcinated, C, S & N-doped TiO2 was successfully synthesized with C/S/N/Ti atomic ratio of 12.5/12.2/1.3/100 and formaldehyde-degradation ratio of 58.5%. Its excited wavelength was red-shifted to 433.5 nm and its band gap was degraded to 2.87 eV. XPS analysis proved that C, S & N was doped into TiO2 lattice to form TiC, Ti(CO)n, Ti(CO3)2, Ti(SO3)2, TiS2, TiN and Ti(NO2)n.
