Efficient Photothermal CO2 Methanation over RuO2/SrTiO3

Transforming CO2 by catalytic hydrogenation is a downhill but kinetically slow reaction. Introducing light is a promising approach to overcoming this kinetic restriction. A new article in Joule by Mateo and colleagues (in press) utilizes Ru-supported titanium perovskite catalysts with sunlight irradiation to achieve record CH4 production rates at low temperatures (~150°C).
