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

Improved photoelectrochemical performance of electrodeposited metal-doped BiVO4 on Pt-nanoparticle modified FTO surfaces

“…Shan et al 65 reported enhanced PEC performance of BiVO 4 upon B-doping attributed to the formation of weak chemical bonds between the B-ions and the corners of the VO 4 -tetrahedron. Additionally, higher photocatalytic activity of B-doped BiVO 4 was observed by Wang et al, 66 who supposed synergetic effects of a number of factors created by B-doping, e.g. higher specic area or more oxygen vacancies.…”

Enhanced photocatalytic activity of S-doped BiVO4photocatalysts

“…According to the electro-neutrality principle, we can deduce that S-doped BiVO 4 samples are oxygen-decient and the amount of surface nonstoichiometric oxygen depends on the surface V 4+ /V 5+ molar ratio. 33 The O1s peak at 530.2 eV (Fig. 3d) is assigned to O 2À species, however, the binding energy of O1s decreases by about 0.4 eV for the S0.5 sample compared with the S0 sample.…”

Co2+ substituted for Bi3+ in BiVO4 and its enhanced photocatalytic activity under visible LED light irradiation

“…Hence, various strategies aiming to enhance the photocatalytic performance of m-s BiVO 4 have been explored. Such approaches could include doping BiVO 4 with metals and/or non-metals, [16][17][18][19][20][21] controlling the morphology and facets of BiVO 4 , 5,13,22,23 constructing a novel p-n heterojunction photocatalyst, [24][25][26][27] and controlling the monoclinic-tetragonal heterostructure of BiVO 4 . 28 Among the many methods for improving the photocatalytic activity, metal and/or non-metal doping is regarded as a simple and effective strategy.…”
