Flame-assisted synthesis of nanoscale, amorphous and crystalline, spherical BiVO4 with visible-light photocatalytic activity

Highly efficient visible light-induced photocatalytic degradation of methylene blue over InVO4/BiVO4 composite photocatalyst

“…This suggests that the fluorescence is from the chemical reactions between terephthalic acid and OH • formed at the composite/water interface via photocatalytic reactions [43]. Moreover, isoelectric point value was analyzed from zeta potential technique for describing photocatalytic enhancement [44]. The isoelectric points of InVO 4 and BiVO 4 catalysts were found to be 2.33 and 4.56, respectively, suggesting that, under the photocatalytic conditions used in this study at pH of 6.5, InVO 4 surface charge was more negative than BiVO 4 .…”

Novel synthesis and photocatalytic performance of BiVO4 with tunable morphologies and macroscopic structures

“…Furthermore, such unique fusiform-like morphology supplies suitable conformation of space that allows incident light to penetrate deep inside the photocatalyst and leads to high mobility of charge, as well as favors adsorption and diffusion of the reactant and product molecules, and thus promotes its photocatalytic performance. On the other hand, it is worth pointing out that a high degree of crystallinity helps to reduce e À -h þ recombination and stimulates the photocatalytic reaction, as reported in the other literature [32]. And it has been reported that the adoption of pure EG as solvent tends to decrease the reaction speed, due to its coordination effect with metal ion, as confirmed in the other literature [33].…”

Mechanochemical synthesis of nanostructured BiVO4 and investigations of related features

“…From structural aspects, BiVO 4 exist in three forms with the features of tetragonal zircon, monoclinic and tetragonal scheelite [7]. The performance of the semiconducting photocatalyst is intimately dependant on the morphology, crystalline phase, preparation method and surface area of the catalyst.…”
