In-situ H2O2 production for tetracycline degradation on Ag/s-(Co3O4/NiFe2O4) visible light magnetically recyclable photocatalyst

Cd-doped Ag2O/BiVO4 visible light Z-scheme photocatalyst for efficient ciprofloxacin degradation

“…Mott–Schottky plots and the CB position of the D1 photocatalyst were generated from the potential vs. NHE (normal hydrogen electrode) data graph. The latter was converted from the potential (in volts ‘V’) vs. Ag/AgCl electrode using the following relation, 28,29 V (NHE) = V (Ag/AgCl) + 0.059pH + 0.197 (here pH = 7)…”

“…15,16 Photoexcitation can concentrate electrons in the less positive CB component and holes in the part with the more positive VB. 28 The latter is called a Z-scheme photocatalyst. It has improved reduction and oxidation driving forces.…”

Fenton reaction by H2O2 produced on a magnetically recyclable Ag/CuWO4/NiFe2O4 photocatalyst

“…Furthermore, they demonstrated that the H 2 O 2 formed in the reaction could degrade tetracycline (by an in situ Fenton-like reaction) in an aqueous medium. 18 Thus, these authors avoided the problems associated with the separation and storage of H 2 O 2 by coupling the production step with another reaction that utilized it for wastewater treatment.…”

The bandgap of sulfur-doped Ag2O nanoparticles

“…Photocatalysis research demands semiconductor nanostructures with appropriate band structures that ensure charge separation and strong redox driving forces. 4–8…”

“…Photocatalysis research demands semiconductor nanostructures with appropriate band structures that ensure charge separation and strong redox driving forces. [4][5][6][7][8] Introducing defects like vacancies or dopants into the parent semiconductor material can increase charge separation and alter the bandgap and adsorption properties. For instance, Hezam et al synthesized oxygen vacancy (OV) enriched ceria (CeO 2 ) with better charge separation and enhanced photocatalytic activity.…”
