Abstract:
Hot carriers and local heating induced by plasmon during its fast-internal relaxation can promote chemical reactions efficiently, and in this way plasmon can turn light energy into chemical energy. By summarizing the theory and experiment improvement about plasmon-drive catalysis on molecules and on nanomaterial transformation, this review aims to introduce physical and chemical mechanisms of localized surface plasmon resonance (LSPR) photocatalysis, including plasmon-induced strong electromagetic field, hot carriers and local heating. However, the microcosmic mechanism of plasmon-driven photocatalysis and models need to be completed, and the technology need to be improved for large scale production.
