Characterization and photocatalytic properties of N-doped BiVO4 synthesized via a sol–gel method

Enhanced visible-light-driven photocatalytic activity of B-doped BiVO4 synthesized using a corn stem template

“…3), while the morphology of 0.04B-BiVO 4 is not templated. Morphology-based effects on photocatalytic activity have also been observed in other studies [9,10,27]. Second, all CS-BiVO 4 samples have smaller crystal sizes and larger specific areas than those of B-BiVO 4 prepared without the CS, explaining the difference in activity between 0.04B-BiVO 4 and 0.04B CS-BiVO 4 even though the B doping content is the same for two samples.…”

“…Doping with nonmetals can improve the charge separation, reduce the band gap energies, and shift the absorption band to the visible region in semiconductor systems [9][10][11]. Our team prepared N-BiVO 4 via a sol-gel method [9]. This work indicated that doping N-atoms into the BiVO 4 lattice, which replaces an O atom and forms an O-Bi-N-V-O bond, contributed to the appearance of a more active V 4 þ species and additional oxygen vacancies.…”

Facile synthesis of nanostructured monoclinic bismuth vanadate by a co-precipitation method: Structural, optical and photocatalytic properties

“…Among the three phases, monoclinic structure shows feasible photocatalytic activity than other structures due to its relatively narrow band gap of 2.4 eV compared to tetragonal structure (3.1 eV) [26]. Monoclinic-BiVO 4 has been synthesized via different methods like homogeneous precipitation [27], co-precipitation [28], surfactant-assisted [29], sonochemical method [30], sol-gel process [31], reverse-micro emulsion technique [32], and hydrothermal treatment [33][34][35][36]. Based on the earlier reports the photocatalytic performance of BiVO 4 mostly depends with crystallite phase governs with (a) visible light property, (b) electronic structure and (c) photocarrier transport properties.…”
