Photocatalytic and Photoelectrochemical Water Splitting on TiO₂ via Photosensitization

Figure 10

Photoelectrochemical properties of TiO₂ NTPC and Au/TiO₂ NTPC and schematic diagram of SPR charge carrier transfer mechanisms. (a) Amperometric I-t curves at an applied potential of 1.23 V versus RHE under illumination of visible light with wavelength ≥420 nm with 60 s light on/off cycles. (b) IPCE plots in the range of 400–700 nm at 1.23 V versus RHE. (c) SPR charge carrier transfer under visible light irradiation at Au/TiO₂ interface. Reproduced with permission from [8].
