From: Monolayered Bi2WO6 nanosheets mimicking heterojunction interface with open surfaces for photocatalysis

Figure 5

(a) Schematic illustration of photocatalytic mechanism over the monolayer Bi2WO6. (b,c) Electron spin resonance signals of DMPO-·OH− adducts and DMPO-O2·− adducts produced by Bi2WO6 samples under visible light irradiation (λ≥420 nm). (d) Photocurrent of Bi2WO6 samples under visible light illumination. (e) Photodegradation of RhB over Bi2WO6 samples (λ≥420 nm). (f) Visible-light-driven photocatalytic H2 evolution over the nanocrystals, monolayers and RhB sensitized monolayers (λ≥420 nm); 0.3 wt% of Pt was loaded.
