Effective degradation of organic pollutants and reaction mechanism with flower-like AgBiO3/g-C3N4 composite

Construction of a novel two-dimensional AgBiO3/BiOBr step-scheme heterojunction for enhanced broad-spectrum photocatalytic performance

“…These assignments are consistent with the standard diffraction patterns of AgBiO 3 (JCPDS 89-9072). 29 For the AgBiO 3 /BiOBr heterojunction, the presence of AgBiO 3 does not affect the BiOBr diffraction peak position (Fig. S1 † ), indicating that AgBiO 3 nanoflowers grew on BiOBr nanosheets without any chemical reaction.…”

“…28 Wu synthesized a novel binary AgBiO 3 /g-C 3 N 4 composite via in situ growth of AgBiO 3 on g-C 3 N 4 , which exhibited improved degradation performance towards organic pollutants of methyl orange (MO), tetracycline (TC), and phenol. 29 More recently, a new step-scheme heterojunction (S-scheme heterojunction) concept was proposed by Yu et al 30 This structure induces the migration of the photo-induced electrons and holes and preserves their redox ability under the influence of an internal electric field due to the differences of the Fermi level of each semiconductor. Wang synthesized S-scheme Sb 2 WO 6 /BiOBr photocatalysts via a precipitation–deposition method, which exhibited enhanced photocatalytic performance compared with pure Sb 2 WO 6 and BiOBr for removal of NO.…”
