The Effects of Reaction Environment on Photocatalytic Methanol Reforming Studied by Operando Nuclear Magnetic Resonance Spectroscopy

Abstract

In this paper, the effects of reaction environment (ambient atmosphere, pressure, gas quantity etc.) on the photocatalytic methanol reforming reaction were studied systematically in a real reaction system using operando nuclear magnetic resonance spectroscopy. It was shown that the ambient atmosphere had differential inhibitory effects on the yields of reaction products, while the environmental pressure and gas quantity had little influences. Based on these observations, the adsorption modes of gases on the catalyst surface were investigated, and a mechanism through which the ambient atmosphere affected the photocatalytic reforming process of methanol was proposed.
