Abstract

(Graph Presented) Photocatalysis is one of the most potential methods to reduce CO2 into useful compounds. In this work, in order to improve the photo reduction of CO2, nickel ions were incorporated in TiO2 and used as photocatalyst. XRD and TEM results showed TiO2 anatase structure with a nanoparticle. The character of surface was measured using BET and zeta potential. The photochemical properties were confirmed by UV-visible and PL. The CO2 reduction was tested in a liquid photoreactor and the products were analyzed in a GC. The highest yield of methane was observed on Ni-TiO2 (0.1 mol%) than that of other catalysts.
