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

Abstract

The development of recyclable H2O2-producing photocatalysts with in-situ Fenton-like organic pollutant degradation is currently a topical area of research. This research investigates the visible light photocatalytic formation of H2O2 on...

In situ use of photocatalytically produced H2O2 for Fenton degradation of organic pollutants

“…Moreover, adding sacrificial agents also enhanced the in situ photo-Fenton degradation of tetracycline. 26 Liu et al reported H 2 O 2 production on the ZnO/Fe 3 O 4 composite consisting of fine magnetite nanoparticles deposited on ZnO microflowers (Fig. 4a and b).…”

“…This issue can be surmounted if the CB location on the photocatalyst has a stronger affinity to oxygen. 26 Similarly, the molecule to be oxidized should have a higher residence time on the location of the photocatalyst VB.…”

Silver nanoparticle-decorated NiFe2O4/CuWO4 heterostructure electrocatalyst for oxygen evolution reactions

“…For comparison, a CuWO 4 sample (the detailed synthesis protocol for the bare CuWO 4 is provided in the supplementary information) was also prepared using this precipitation method. 37 Paper PCCP…”

Interfacial engineering of CuWO4/WO3 thin films precisely fabricated by ultrasonic spray pyrolysis for improved solar water splitting

“…15–17 However, the PEC performance of CuWO 4 photoanodes is seriously impeded by the poor charge transfer and slow surface reaction kinetics. 18,19 Up to date, numerous strategies including controlling the morphology, 20 doping with exotic elements, 21 establishing heterojunctions, 22–24 loading with precious metals, 25 and incorporating with surface cocatalysts, 26 have been proposed to improve the PEC performance of CuWO 4 photoanodes. Particularly, constructing heterostructures with a built-in electric field is one of the most effective strategies to accelerate photogenerated charge separation and transfer.…”
