Combinatorial Photoactivity Enhancement of Ternary Nanohybrids: Ag Cocatalyst-Dispersed Monoclinic Bi2O3/g-C3N4 through the Synergistic Action of Induced Oxygen Defect and Porosity for Abatement of Fluoroquinolones and Boosted Antimicrobial Activity

“…However, in its pristine form, it shows poor photocatalytic performance owing to a high charge recombination rate. 12 As per a recent work on fluoroquinolone ciprofloxacin degradation by Ma et al, visible-light photoactivity of heterostructure BO/TiO 2 and separation of charge carriers were significantly more than their precursors. 13 This idea was supported by Sarkodie et al 14 and Gao et al, 15 who stated that building heterostructures using BO and alteration in its morphology largely impact the degradation statistics.…”

“…The varying band-gap range of 2.0−3.9 eV demonstrates notable photoconductivity. 12 Additionally, BO is an effective photoresponsive catalyst owing to its easy synthesis procedure, abundance in natural reserves, and flexible electronic framework. Moreover, it exhibits polymorphism that includes six polymorphs comprising four metastable phases (β, γ, ϵ, ω) and two stable phases (α, δ), among which the α-phase shows the highest stability.…”
