▎ 摘　　要

NOVELTY - Preparation of light-driven thermoelectric nanogenerator involves spin-coating silver nanowire solution on polarized polyvinylidene fluoride film substrate, forming a silver nanowire layer, transferring graphene layer on surface of the silver nanowire layer by unsupported layer transfer method, and obtaining composite surface-enhanced Raman spectroscopy substrate with plasmon structure coupled with thermoelectric material. USE - Preparation of light-driven thermoelectric nanogenerator used as surface-enhanced Raman spectroscopy substrate for in-situ detection catalysis (all claimed). ADVANTAGE - The method enables preparation of light-driven thermoelectric nanogenerator having excellent thermoelectric effect, thermal charge density of plasmon layer, plasmon effect and strength. The thermoelectric nanogenerator is easy to operate, and stably realizes monitoring of catalytic process.
