Anatase TiO2 nanosheets with {001}-{101} surface heterojunction is employed as the typical photocatalyst to study surface plasmon resonance (SPR) enhanced photocatalytic Cr(VI) reduction with the help of selectively deposited Au and Pt nanoparticles. By employing an UV LED with central wavelength of 365 nm and a green LED with central wavelength of 530 nm as the light sources, results indicate the single green LED has little positive effect on driving the photocatalytic Cr(VI) reduction. In contrast, Au SPR can significantly improve the photocatalytic Cr(VI) reduction efficiency when both the UV LED and green LED are simultaneously irradiated. The {001}-{101} surface heterojunction and Pt nanoparticles can further improve the Cr(VI) reduction efficiency because of the facilitated hot electrons' transfer. Our findings suggest that the synergistic effect among {001}-{101} surface heterojunction, Au/Pt selective deposition, and excitation wavelength is important for SPR enhanced photocatalytic Cr(VI) reduction activity.
