Summary:New type of ternary NiAlCe layered double hydroxide photocatalyst was synthesized by a simple hydrothermal reaction. The obtained photocatalyst shows efficient visible-light activity for CO2 reduction to CH4. We have investigated the optimal Ce content in the catalyst and analyzed the mechanism by materials characterization. Additionally, a novel alkali etching method was used to construct the porous structure. The effect of the porosity and morphologies on the activity is investigated. It is found that the ternary NiAlCe layered double hydroxide photocatalyst with porosity showing the best photocatalytic activity among all the samples. Based on the characterization and first principle calculation, the detailed photocatalytic mechanism of the ternary NiAlCe layered double hydroxide photocatalyst is deduced.
