The paper investigates the light-driven Sabatier reaction over Ru films sputtered onto silica opal (Ru\/SiO2) and inverted silicon opal photonic crystal (Ru\/i-Si-o) supports. Under ambient temperature conditions, photomethanation rates over both the Ru\/SiO2 and Ru\/i-Si-o catalysts were shown to increase significantly with increasing light intensity, and rates as large as 2.8 mmol g\u22121 h\u22121 are achieved over the Ru\/i-Si-o catalyst. Furthermore, the quantum efficiency of the photomethanation reaction was found to be almost three times larger when measured over the Ru\/i-Si-o catalyst as compared to the Ru\/SiO2 catalyst. DFT analysis indicate that charged Ru surfaces can destabilize adsorbed CO2 molecules and adsorb and dissociate H such that it can readily react with CO2, thereby accelerating the Sabatier reaction.
