Abstract:A new visible-light responsive metallic photocatalyst, nanostructured MoO2, has been discovered. The metallic nature of MoO2 is confirmed by valance X-ray photoelectron spectroscopy spectrum and theoretical calculations. However, MoO2 itself shows only moderate activity due to the serious charge recombination, a general disadvantage of metallic photocatalysts. The findings suggest that its effective charge diffusion length L-p is smaller than 1.0 nm while the separation efficiency (sep) is less than 10%. Therefore, only the periphery of the metallic MoO2 can effectively contribute to photocata
