Description
TiO2-In2O3 (Ti-In) was synthesized by the sol-gel method and the composite was further doped with nitrogen and carbon to create Ti-In-N and Ti-In-C, respectively. The dye C.I. Reactive Red 2 (RR2) was used a model compound to be subjected to various composites and measured for removal by photocatalytic degradation and adsorption. Ti-In-N possessed a larger mean diameter than Ti-In-C, while the latter possessed a greater anatase content and surface area than the former. After N or C doping, the spectra of corresponding Ti-In-N and Ti-In-C showed absorption edges at longer wavelengths than the parent Ti-In. Ti-N-O and Ti-O-C bonds were found in Ti-In-N and Ti-In-C composites, respectively. Ti-In-N was more effective for RR2 photodegradation than Ti-In-C, and the Ti-In-C removed more RR2 by adsorption than Ti-In-N
