Solvothermal synthesis of biochar@ZnFe2O4/BiOBr Z-scheme heterojunction for efficient photocatalytic ciprofloxacin degradation under visible light

A biochar-promoted V2O5/g-C3N4 Z-Scheme heterostructure for enhanced simulated solar light-driven photocatalytic activity

“…The large amount of BC of 15% BC affects the absorption and reection of UV and visible light, which leads to abnormal phenomenon of RhB degradation. In addition, with the increase of BC doping, the band gap becomes narrower and narrower, which may be due to the band gap mixing effect of the two and the interaction of the two semiconductors at the interface, thereby introducing the level of defects 37 or the increase in BC content and the accompanying increase in function groups affecting the crystalline morphology of g-C 3 N 4 and V 2 O 5 . 38 PL analysis was carried out to investigate the separation and the transfer ability of photoinduced charge carriers.…”

Synergistic photocatalytic effect of BiOBr–BiOI heterojunctions due to appropriate layer stacking

“…1a and b. The BiOBr films match with the standard ICDD file PDF 01-085-0862, 32 and the BiOI films match with the standard ICCD file PDF 01-073-2062. 33 All patterns correspond to the tetragonal crystal system with the space group P4/ nmm (129).…”

Novel BiOBr by compositing low-cost biochar for efficient ciprofloxacin removal: the synergy of adsorption and photocatalysis on the degradation kinetics and mechanism insight

“… 41 Its degradation efficiency was higher than that of the biochar@ZnFe 2 O 4 /BiOBr composite material for CIP (84%), indicating that the material has better photocatalytic performance. 37 …”
