Photocatalytic performance and reaction kinetics — Caption

(a) The C2H6 to CO2 ratios of Pt/Ga2O3 and Pd/Ga2O3 photocatalysts. The Pd cocatalyst promotes C2H6 formation more efficiently than the Pt cocatalyst. Methane pressure dependence on the formation rates of CO2 and C2H6 over (b) Pt/Ga2O3 and (c) Pd/Ga2O3 photocatalysts at ~323 K. The pressure of water vapor was fixed at 2 kPa. Schematic illustration of photocatalytic methane oxidation and reduction taking place on (d) Pt and (e) Pd cocatalysts covered with a single water layer.
