Abstract

A wet-chemical technique was used to synthesize InTaO ₄, AgNbO ₃, InNbO ₄, and various metal doped InTaO ₄ catalysts. Their physicochemical properties were characterized by UV-vis diffusion reflectance spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). Photocatalytic activities of these materials were evaluated in liquid-phase decomposition of methylene blue and phenol as well as gas-phase degradation of toluene under UV-vis light. InTaO ₄ exhibited higher activity than AgNbO ₃ and InNbO ₄ in photodecomposition of organic compounds in gas and liquid phases. Ni-doping could enhance the photocatalytic activities. Commercial TiO ₂-P25 had better activity, but Ni-InTaO ₄ showed more stable performance in catalytic oxidation of toluene.
