Recent Advances in Localized Surface Plasmon Resonance Materials for Enhanced Photothermal Catalytic Reverse Water-Gas Shift Reaction.

With the rapid growth of the human society, the concentration of CO₂ in the atmosphere has caused serious environmental problems. Photothermal catalytic reverse water-gas shift (RWGS) reactions, as an efficient and green pathway for CO₂ conversion, has received widespread attention. Localized surface plasmon resonance (LSPR) materials have shown great potential in the field of photothermal catalysis due to their unique physical, chemical, and optical properties. This review summarized the research progress of LSPR materials in photothermal catalytic RWGS reactions. First, the characteristics and mechanism of photothermal catalytic RWGS reactions are introduced. Then, the basic principles and characteristics of LSPR materials are displayed, including their LSPR effect and the resulting photothermal conversion ability. Furtherly, the recent development of LSPR materials for photothermal RWGS reactions were compared in terms of their reaction activity, selectivity, and reaction mechanism. Finally, the existing problems in current research were discussed, and future research directions were proposed. By conducting in-depth research on the role of LSPR materials in the photothermal catalytic RWGS reactions, new ideas and methods are provided for achieving efficient and sustainable energy conversion, promoting the development of energy utilization.
