The InTaO₄ materials were prepared by a facile sol–gel route, and Ni nanoparticles were loaded by the photodeposition method. Prepared materials were characterized by X-ray diffraction, ultraviolet, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. InTaO₄ shows CO₂ reduction under visible light irradiation. Using Ni/InTaO₄ as heterogeneous catalysts, the photocatalytic performance of CO₂ to methanol conversion was remarkably enhanced. Loading of Ni slightly reduces the band gap and may help to slow the recombination process, which provides a higher yield of methanol.
