Facile synthesis of V4+self-doped, [010] oriented BiVO4nanorods with highly efficient visible light-induced photocatalytic activity

Abstract: Monodispersed monoclinic BiVO4 nanorods grown along the [010] direction were prepared using a one-step low temperature hydrothermal method in the presence of the low-cost, nontoxic sodium oleate serving as a chelating agent. The BiVO4 nanorods with diameters of 15-20 nm possess a huge specific surface area as large as 28.2 m(2) g(-1), which can endow them with high photocatalytic activity and strong adsorption of reactants. Meanwhile, the specific [010] growth direction is capable of facilitating efficient ele… Show more

“…14 The calculated oxidation potential may be more negative than the calculated valance edge of the material, as veried by the previous literature. 14 Hence, great efforts have been made to improve the photocatalytic properties of BiVO 4 , e.g., developing heterojunctions, [15][16][17] designing morphologies, [18][19][20][21][22] doping ions, [23][24][25] and facet selective deposition. 26,27 The morphology design is the most commonly used way to improve the electron transfer of BiVO 4 photocatalysts.…”

“…However,e xcessive V 4+ is detrimental to the PEC performance of BiVO 4 ,b ecause larger radius of V 4+ acts as scattering centers and reduce the diffusion length of holes. [14] Obviously,i ti sv ery challenging to tune the content of V 4+ to achieve efficient BiVO 4 photoanodes via hydrogenation or chemical reduction. Note that hydrogenation requires pure H 2 flowing at high temperature, [12] which would increase the fabrication hazard and cost as well.…”

“…This result can be explained by existence of oxygen vacancies resulted from the change in local coordination environments of Bi 3 + and V 5 + (thus generating V 4 + species). [33][34][35] The O 1s signal of each sample was decomposed into three components at BE = 529.7-530.0, 531.0-531.3, and 532.9-533.1 eV, attributable to the surface lattice oxygen (O latt ), adsorbed oxygen (O ads ), and adsorbed water species, respectively. [36] We can observe from Figure S3 that the O ads concentration increased with the rise in Ru loading of Ru/3DOM BiVO 4 .…”
