Thermal Management Materials and Strategies for Photothermal Catalysis

Abstract As an innovative approach to the utilization of solar energy, photothermal catalysis is based on the principle of generating localized high temperature at the site of light‐absorbing materials, which then drive subsequent catalytic reactions. This process has significant implications for alleviating energy shortages and protecting the environment. Thus far, considerable attention has been devoted to the development of catalytic materials, while the heat transfer process throughout the entire material system receives comparatively little consideration. However, the heat transfer process plays a pivotal role in regulating the photothermal temperature, and its behavior can be further effectively manipulated through the implementation of advanced thermal management materials. In this perspective, the fundamental principles of photothermal catalysis are elucidated, with particular emphasis on the pathways of heat dissipation process. Subsequently, the recent research progress of thermal management materials and strategies in increasing photothermal temperature is summarized from the aspects of conduction, convection, and radiation. Finally, the obstacles and challenges encountered throughout the ongoing research are discussed, and further efforts are proposed for designing high‐performance photothermal catalytic systems by thermal management. This perspective is expected to provide guidance for the application of thermal management materials and strategies in photothermal catalysis.
