Herein, Pt/TiO2 and Au/TiO2 catalysts were synthesized by photodeposition method, CO2 photothermal reduction performance, physicochemical characterization, photochemical characterization in situ mechanism experiments performed on with different Pt Au loading ratios. The results showed that the of can effectively enhance optical absorption characteristics TiO2, which is due to strong metal–semiconductor interaction plasmon resonance effect surface noble metal nanoparticles. PT-0.4 AT-2 had a relatively stronger conversion ability. In addition, load mainly enhances selective CH4, while CO. However, nanoparticles are prone agglomeration, reduces catalytic activity, stable. Mechanism study have similar intermediate species dark adsorption light reaction stages, but achieves CH4 generation through such as *CHO, key CO *COOH.
