Abstract: Recently, the plasmon-induced surface photo-catalytic reaction attracts more and more attention in the area of organic chemistry and the environmental sciences, because it can improve the photo-oxidation and reduction and the selectivity of reaction by electron-transfer and energy-transfer processes under excitation of sun-light.Some fundamental problems in the field of plasmon photo-catalyst have been discussed in this paper on the base of the recent international literatures. The discussed topics include:the LSPR formation under excitation of noble-metallic nano-particles by visible light and the electron-transfer between noble-metal and semi-conductor; the plasmon induced resonance energy transfer (PIRET) between plasmon particle and semi-conductor; and the effect of structure and components of plasmon catalyst on the catalytic ability of catalysts.

Key words: localized surface plasmon resonance (LSPR), plasmon photo-catalyst, electron transfer, plasmon induced resonance energy-transfer (PIRET), titanium dioxide
