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.

High‐performance heterogeneous thermocatalysis caused by catalyst wettability regulation are summarized, including the introduction of hydrophilicity, hydrophobicity, hybrid hydrophilicity‐hydrophobicity, amphiphilicity, and superaerophilicity. Relevant reactions are classified and described in detail according to the reason for the performance improvement. Studies of utilizing superaerophilicity to improve heterogeneous thermocatalytic performance have been included in the system for the first time, forming a comparatively comprehensive review in this field as yet.
