To optimize solar energy utilization, photothermal materials are engineered to maximize incident solar radiation absorption, while minimizing losses due to transmission and reflection. Furthermore, these materials are designed to convert absorbed photon energy into thermal energy efficiently.
In this review, we first introduce the fundamental principles of photothermal catalysis, including different mechanisms of photothermal conversion (i.e., plasmonic localized heating, non-radiative relaxation of semiconductors, and thermal vibration in molecules) and different types of photothermal catalytic processes.
A photothermal process is a direct conversion of solar light, which can exhibit maximally achievable efficiency of energy conversion compared with other solar energy utilization technologies.
Thermal Management Effective thermal management is essential in enhancing the efficiency of photothermal conversion systems, which convert solar energy into thermal energy. Here, we discuss strategies to improve thermal management by focusing on insulation, heat transfer mechanisms, and materials selection.
Unveil the three mechanisms of photothermal conversion: plasmonic localized heating, molecular thermal vibration, and non-radiative relaxation. Illuminate the foundational principles directing the design of photothermal nanomaterials for optimized performance and functionality.
This mechanism is paramount across many applications, facilitating the exploitation of solar energy for different purposes. The photothermal conversion efficiency and applications are fundamentally contingent upon the characteristics and performance of the materials employed.
