Precise regulation of the selectivity of supported nano-Pd catalysts using polysiloxane coatings with tunable surface wettability

Abstract

A facile method was developed for surface modification of supported nano-Pd catalysts with tailorable wettability. The obtained Pd/TiO₂@POS catalytic materials could be used in the controllable synthesis of styrene and ethylbenzene obtained from hydrogenation of phenylacetylene and the selective synthesis of imine and N-methylanilines via a reductive amination reaction. The precise modification of the hydrophilicity/hydrophobicity of the catalyst surface is crucial to realize this targeted transformation.
