Continuous flow photoassisted CO2 methanation

[EN] Photoassisted CO2 methanation using Ni-Al2O3/SiO2 as a photoresponsive catalyst has been carried out at 225 degrees C under continuous flow conditions achieving up to 3.5% conversion of CO2 with complete selectivity to CH4 under 2327 W m(-2) irradiation for a contact time of 1.3 s. An apparent quantum yield of 0.11 was estimated for the continuous flow process.Financial support by the Spanish Ministry of Economy and Competitiveness (Severo Ochoa and CTQ2015-65169-CO2-R1) is gratefully acknowledged.
