Abstract

A novel Schiff (Mo) base complex supported on GO surface was successfully prepared, which was further combined with graphitic carbon nitride (g-C₃N₄) polymer (Mo-GO/g-C₃N₄) to make it photo-active. The photocatalytic activity of the resulting nano-composite was tested under simulated sunlight (AM 1.5) for the epoxidation of various olefin substrates. In addition, surface photovoltage (SPV) measurements were applied to explore the electron acceleration effect caused by GO and molybdenum. It was demonstrated that both GO and the metal active centers can efficiently accelerate electron transfer, which would finally contribute to the superior catalytic performance.
