Anatase-type titania nanoparticles co-doped with niobium and gallium (GaXTi1−2XNbXO2 solid solutions in the range of X = 0–0.20) were formed from precursor solutions of TiOSO4, NbCl5, and Ga(NO3)3 under hydrothermal conditions at 180°C for 5 h using the hydrolysis of urea. The effect of dopant materials on the structure, crystallite growth, photocatalytic activity, and phase stability of anatase-type TiO2 was investigated. The lattice parameters a0 and c0 of anatase slightly and gradually increased with increase in niobium and gallium content doped into TiO2. The anatase solid solutions doped with niobium and gallium (X = 0.10–0.15) showed good photocatalytic activity. Co-doping niobium and gallium into TiO2 shifted the anatase-to-rutile phase transformation to lower temperature. The temperature range of the anatase-to-rutile phase transformation for the GaXTi1−2XNbXO2 solid solutions became narrower than that for pure TiO2. The rutile-type GaXTi1−2XNbXO2 solid solutions were formed via the phase transformation.
