Tribocatalysis: a successful marriage of triboelectricity and heterogeneous catalysis

Abstract

Tribocatalysis is an emerging and promising approach that integrates triboelectric effects with heterogeneous catalysis to drive chemical reactions through mechanical energy input. In contrast to conventional catalytic methods that rely on thermal, photonic, or electrical stimuli, tribocatalysis utilizes friction-induced charge generation as a sustainable and energy-efficient means of activating catalytic processes. This article discusses the underlying principles of tribocatalysis, with particular emphasis on the dual function of mechanical stirring in facilitating catalyst–substrate interactions and promoting catalyst activation. Key materials and activation mechanisms are reviewed, highlighting their potential in applications such as environmental remediation and chemical energy storage. Despite recent advances, significant challenges remain, including limited mechanistic insight, issues of material durability, and difficulties in scaling up. This work aims to provide a comprehensive perspective on the current state of tribocatalysis, identify critical knowledge gaps, and encourage continued research to advance the field toward practical implementation.
