Facile fabrication of a novel BiPO₄ phase junction with enhanced photocatalytic performance towards aniline blue degradation

Abstract

A novel BiPO4 photocatalyst has been fabricated via a facile precipitation route using dimethyl sulfoxide (DMSO) as a solvent.

Ultrafast conversion of carcinogenic 4-nitrophenol into 4-aminophenol in the dark catalyzed by surface interaction on BiPO4/g-C3N4 nanostructures in the presence of NaBH4

“…The details of the synthesis of BiPO 4 were reported in our previous study. 51 Typically, 1.94 g of Bi(NO 3 ) 3 ·5H 2 O and 0.5 g CTAB were stirred in 40 mL dimethyl sulfoxide. Then 0.524 g (NH 4 ) 2 HPO 4 dissolved in 40 mL of water was dropped into the previous solution under vigorous stirring for 1 h. After the formation of precipitate, the solid was recovered with centrifugation, and then washed with water and ethanol, and finally it was dried for 6 h at 90 °C.…”

Bismuth and Vanadium-Substituted Yttrium Phosphates for Cool Coating Applications

“…The peaks at 501 cm −1 corresponding to bending mode of the PO 4 group and the band at 196 cm −1 could be due to O−Bi−O bending mode of vibrations. 38,39 VO 4 stretching vibrations are observed at 841 cm −1 . 40 Significant vibrations indicate the presence of metal oxide bonding, phosphate, and vanadate moiety in the YB2V2 material.…”

Defect physics of intrinsic point defects in BiPO4 photocatalysts: a hybrid functional study

“…Therefore, there are many experiments to improve the photocatalytic activity of BiPO 4 . For instance, it was reported that the formation of an nMBIP-mMBIP phase junction obviously enhanced the photocatalytic activity of BiPO 4 ; 22,24,25 Yang et al illustrated that BiPO 4 in combination with other materials such as graphene aerogel (GA) could also improve its photocatalytic activity and increase the degradation rate of methylene blue (MB). 26 Among the many methods to enhance the photocatalytic performance of BiPO 4 and other semiconductor photocatalysts, defect introduction and control (including intrinsic defects and doping) of photocatalysts is a widespread and usual method.…”
