Abstract

In the past decades, water tolerance has always been the long-pending key issue of sulfated solid superacids (SO42–/MxOy) toward industrial applications. Herein, we report a strategy for the facile coating of a thick tunable hydrophobic layer over SO42–/MxOy, which can significantly improve water tolerance, with negligible inhibition on the catalytic performance of SO42–/MxOy. Even after being directly immersed in water, the hydrophobic SO42–/MxOy can still maintain above 90% of original catalytic activity, whereas pristine SO42–/MxOy and control samples are almost completely deactivated. This strategy opens a new route to enhance the water tolerance of sulfated solid superacids.
