The n-p coupled semiconductor materials Cu/TiO₂-NiO were prepared by a sol-gel method, TG-DTA, TPR, as well as XRD, TEM and UV-Vis were used to characterize the crystal structure and photo absorbing ability of the precurors and final catalysts, respectively. The Photo Stimulated Surface Reaction(PSSR) of CO₂ and H₂O on Cu/TiO₂-NiO has been investigated. The results revealed that CH₃OH, CH₄ and CO can be produced by PSSR at normal temperature with high selectivity of CH₃OH. The composition of the material shows significant effects on the PSSR. The highest CO₂ conversion was obtained on 0.50% Cu/TiO₂-2.0% NiO catalyst.
