Efficient hole abstraction for highly selective oxidative coupling of methane by Au-sputtered TiO2 photocatalysts

Efficient hole abstraction for highly selective oxidative coupling of methane by Au-sputtered TiO2 photocatalysts Abstract Photocatalytic oxidative coupling of methane (OCM) produces C 2 molecules that can be used as building blocks for synthesis of fuels and chemicals. However, the yield rate and the selectivity of C 2 products are still moderate due to the stable nature of methane molecules. Here we develop a Au nanocluster-loaded TiO 2 photocatalyst by a sputtering approach, achieving a high...
