High‐Performance Heterogeneous Thermocatalysis Caused by Catalyst Wettability Regulation

Abstract

Catalyst wettability regulation has emerged as an attractive approach for high catalytic performance for the past few years. By introducing appropriate wettability, the molecule diffusion of reactants and products can be enhanced, leading to high activity. Besides this, undesired molecules are isolated for high selectivity of target products and long‐term stability of catalyst. Herein, we summarize wettability‐induced high‐performance heterogeneous thermocatalysis in recent years, including hydrophilicity, hydrophobicity, hybrid hydrophilicity‐hydrophobicity, amphiphilicity, and superaerophilicity. Relevant reactions are further classified and described according to the reason for the performance improvement. It should be pointed out that studies of utilizing superaerophilicity to improve heterogeneous thermocatalytic performance have been included for the first time, so this is a comparatively comprehensive review in this field as yet.

Amine-Functionalized Hydrophobic Cross-Linked Polymer-Supported Palladium Nanoparticles: An Efficient Catalyst for the Selective Hydrogenation of Citral to Citronellal

“…synthesized superhydrophobic polymer films by regulating the proportion of styrene and n -butyl acrylate at different temperatures . In our previous works, we also demonstrated that the hydrophobicity of catalysts was helpful for hydrogenation reactions. − However, to the best of our knowledge, there is no study using a hydrophobic catalyst for the selective hydrogenation of citral to citronellal reaction.…”
