The role of surface hydroxyl groups on a single-atomic Rh<sub>1</sub>/ZrO<sub>2</sub> catalyst for direct methane oxidation

Abstract
could be reduced with enhanced methanol productivity in the presence of the surface hydroxyl groups. The formation of the surface hydroxyl groups upon hydrothermal treatment and their disappearance upon reaction were confirmed with diffuse reflectance infrared Fourier transform spectroscopy, indicating that the surface hydroxyl groups participate in the surface reaction.
