A carnation-like rGO/Bi2O2CO3/BiOCl composite: efficient photocatalyst for the degradation of ciprofloxacin

The controlled synthesis of g-C3N4/Cd-doped ZnO nanocomposites as potential photocatalysts for the disinfection and degradation of organic pollutants under visible light irradiation

“…Ammonium oxalate (AO), benzoquinone (BQ), and isopropanol (IPA) scavengers were used as capture agents to remove photogenerated h + , cO 2À , and cOH radicals, respectively. 41,42 When benzoquinone (BQ) was added to the dye solution, the Fig. 11 (a) Natural logarithm and (b) inverse of natural logarithm with the rate of the change in concentration with time for the 7% Cd-ZnO NPs, (25%, 50%, 55%, 60%, and 65)% g-C 3 N 4 /Cd-ZnO and 60% g-C 3 N 4 /ZnO NCs.…”

The rGO/BiOBr/Bi4O5Br2 Composites with Stacked Nanosheets for Ciprofloxacin Photodegradation under Visible Light Irradiation

“…The catalysts with the rGO addition of 0.5 and 2.0 wt% obtained less than half of the photocatalytic activity with rGO amount of 1.0 wt%. In the similar reports, the composites achieve optimum photodegradation activity with the rGO amount of 1 wt% , , . Hence, the rGO amounts were regulated among 0.9, 1.0 and 1.1 wt%.…”

“…Under visible light irradiation, the rGO/BiOBr/Bi 4 O 5 Br 2 composites absorb the energy to generate electron‐hole pairs . The rGO can reduce the recombination of electron‐hole pairs by transferring photo‐induced electrons , , . Then the electrons transferred rapidly from conduction band to rGO.…”

Synthesis and characterization of CeO2/Bi2O3/gC3N4 ternary Z‐scheme nanocomposite

“…These radicals react with the MG and the degradation of dye takes place fast. But when a scavenger is added, a gradual decrease in the degradation of dyes takes place due to the quenching of reactive species 44,45 …”
