【 摘 要 】

In this paper, we design and fabricate a NanoFinger Plasmonic Structure (NFPS) utilized in water splitting for hydrogrn production by visible light irradiation. This structure can generate numerous hot electrons from localized surface plasmon resonance (LSPR) during visible light irradiation. Through this hot electrons transferred via titanium dioxide to platinum nanoparticles, hydrogen ions in water can be efficiently reducing into hydrogen, while hot holes left in gold oxidizing into oxygen. Experimental results demonstrated the photoelectrochemical signal can be enhanced by 1.96∼2.09-fold in on-off test under visible light, indicating the possibility for high efficient hydrogen generation.
