Title
Novel Ti-KIT-6 material for the photocatalytic reduction of carbon dioxide to methane
Abstract

•Synthesis of novel Ti-KIT-6 materials (Si/Ti ratios = 200, 100, 50)•Characterization by BET, TEM, FT-IR, and XPS analysis•Methane production through photocatalytic reduction of CO2 over Ti-KIT-6•Effects of Ti content and distribution over KIT-6, OH groups on the activity•Activity comparison of optimized Ti-KIT-6 with commercial Degussa P25 TiO2

Novel Ti-KIT-6 materials with different Si/Ti ratios (200, 100 and 50) have been synthesized, characterized and applied for the photocatalytic reduction of carbon dioxide to methane. An intermediate amount of Ti(Si/Ti = 100) was found to be isolated and uniformly distributed, without collapsing the KIT-6 structure. TiO2 formation was observed due to a higher amount of Ti(Si/Ti = 50). Overall, the Ti-KIT-6 (calcined) materials were superior in activity than the Ti-KIT-6 (dried) materials. Owing to the greater number of OH groups, the Si/Ti ratio of 100 showed a higher methane production rate and was found to be more reactive than commercial Degussa P25 TiO2.
