The visible-light-driven photocatalytic reduction of Cr using BiVO: assessing the effect of Au deposition and the reaction parameters.

In this work, fern-leaf-like BiVO was used to photocatalytically reduce Cr in water. Nanosized BiVO displayed bandgap energy and specific surface area of 2.49 eV and 5.

Electronic and optical competence of TiO/BiVO nanocomposites in the photocatalytic processes.

Nanocomposites with different ratios of titanium dioxide and bismuth vanadate [TiO]/[BiVO] give rise to compatible electronic band structure alignment at their interfaces to ensure enhanced photoactivated charge transfer under visible light. The sol-gel method and suitable post-synthesis thermal treatments were used to synthesize different compositions with stabilized anatase phase of TiO and monoclinic scheelite polymorph BiVO. Structural, electronic and optical characterizations were performed and the results were analysed as a function of the stoichiometry, in which both crystalline structures show a clear junction formation among their characteristic stacking planes.
