Toward innovative photothermal catalysis

2025

Abstract

This chapter introduces gas-solid heterogeneous photothermal catalysis as a novel approach for advancing the field of heterogeneous catalysis. It begins by explaining the fundamental insights into charge carriers and heat generation under light and their integration for photothermal excitation. It then explores the advantages of light-heat dual activation in achieving efficient and selective catalysis. Following this, the chapter discusses innovative catalyst design strategies aimed at enhancing energy efficiency for next-generation light-powered chemical productions. Finally, we examine the scalability of photothermal catalysis based on recent research advances, techno-economic analysis, and pilot scale demonstrations.

Efficient energy use

Efficient energy use, sometimes simply called energy efficiency, is the process of reducing the amount of energy required to provide products and services. For example, insulating a building allows it to use less heating and cooling energy to achieve and maintain a thermal comfort. Installing light-emitting diode bulbs, fluorescent lighting, or natural skylight windows reduces the amount of energy required to attain the same level of illumination compared to using traditional incandescent light bulbs.

Heterogeneous catalysis

Heterogeneous catalysis is catalysis where the phase of catalysts differs from that of the reactants or products. The process contrasts with homogeneous catalysis where the reactants, products and catalyst exist in the same phase. Phase distinguishes between not only solid, liquid, and gas components, but also immiscible mixtures (e.g. oil and water), or anywhere an interface is present. Heterogeneous catalysis typically involves solid phase catalysts and gas phase reactants.

Homogeneous catalysis

In chemistry, homogeneous catalysis is catalysis where the catalyst is in same phase as reactants, principally by a soluble catalyst a in solution. In contrast, heterogeneous catalysis describes processes where the catalysts and substrate are in distinct phases, typically solid-gas, respectively. The term is used almost exclusively to describe solutions and implies catalysis by organometallic compounds. Homogeneous catalysis is an established technology that continues to evolve.
