Silica, nitrogen, and nitrogen-plus-silica co-doped titania powders were synthesized via sol-gel method. Nitrogen, silica, and co-doping shifted the anatase-to-rutile phase transition toward higher temperatures. Silica was found to enter the anatase lattice, and nitrogen was presumed to enter thetitania crystal structure as well. Nitrogen doping and SiO2/N-co-doping shifted the light absorption toward the visible region.
