New insights into the surface plasmon resonance (SPR) driven photocatalytic H₂ production of Au-TiO₂.

ABSTRACT: The Surface Plasmon Resonance (SPR) driven photocatalytic H₂ production upon visible light illumination (≥500 nm) was investigated on gold-loaded TiO₂ (Au-TiO₂). It has been clearly shown that the Au-SPR can directly lead to photocatalytic H₂ evolution under illumination (≥500 nm). However, there are still some open issues about the underlying mechanism for the SPR-driven photocatalytic H₂ production, especially the explanation of the resonance energy transfer (RET) theory and the direct electron transfer (DET) theory. In this contribution, by means of the EPR and laser flash photolysis spectroscopy, we clearly showed the signals for different species formed by trapped electrons and holes in TiO₂ upon visible light illuminat
