Novel degradation of amoxicillin by WO3/Ag3VO4 Z-scheme heterojunction deposited on rGO

Recent advances in removal of pharmaceutical pollutants in wastewater using metal oxides and carbonaceous materials as photocatalysts: a review

“…A WO 3 /Ag 3 VO 4 Z-scheme heterojunction with enhanced separation efficiency of electron–hole and surface area was deposited on rGO and used as a photocatalyst in the degradation of amoxicillin under irradiation by visible light. 212 The amoxicillin photocatalytic degradation followed the following order on irradiating it with visible light: Ag 3 VO 4 /WO 3 /r-GO (∼96%) > Ag 3 VO 4 /WO 3 (∼37%) > WO 3 > Ag 3 VO 4 (∼32%). It is suggested that the presence of rGO, by increasing the surface area in Ag 3 VO 4 /WO 3 /rGO, facilitates amoxicillin adsorption and electron transfer for charge separation of Ag 3 VO 4 /WO 3 .…”

“…Hence, it is necessary to conduct a large amount of research on the treatment and removal of amoxicillin from wastewater using a variety of photocatalysts before discharging it into the natural aquatic environment. 149–216…”

TiO2 Deposited on Activated Sewage Sludge for Effective Photocatalytic Degradation of Tetracycline

“…Currently, several techniques, such as biological treatment [14,15], advanced oxidation technologies [16,17], electro-chemical treatment [18,19], filtration [20,21], adsorption [22], and photocatalytic degradation have been applied to remove antibiotics from aqueous media [23,24]. Among them, adsorption and photocatalytic degradation have been especially preferred due to their high efficiency, relatively low cost, and environmental friendliness [25].…”
