摘　　要：等离激元弛豫产生的热载流子以及局域热效应能有效地驱动材料的化学反应,将光能转化为化学能,从而实现等离激元诱导的光催化。对等离激元诱导分子化学反应和晶体结构转变的相关理论和实验进展进行了综述,重点讨论了等离激元驱动分子反应和驱动纳米结构变化诱导光催化的物理和化学机制,包括等离激元增强电磁场、热载流子、局域热效应等诱导过程,并指出了等离激元催化微观理论模型的不足和实现大规模工业生产的技术瓶颈。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.
