Visible light activated V2O5/rGO nanocomposite for enhanced photodegradation of methylene blue dye and photoelectrochemical water splitting

Enhanced Photocatalytic Degradation Activity Using the V2O5/RGO Composite

“…The superior photocatalytic performance of the V 2 O 5 /rGO composite photocatalyst is attributed to enhanced light absorption capacity, effective charge transfer, and minimum charge recombination, etc. In addition, a large number of active sites are available for redox reactions as compared to the V 2 O 5 photocatalyst [ 11 , 16 , 35 ]. Active sites are responsible for the generation of highly reactive hydroxyl and superoxide radicals that react with organic impurities and mineralize them into CO 2 and H 2 O.…”

“…[ 10 ]. However, despite outstanding success in this field during the past few decades, but there are still major challenges to developing efficient, cost-effective, and robust materials, which are able to absorb visible light with good carrier conductivity, band positions, and stability, during photochemical reactions [ 11 ].…”

“…Chauhan et al synthesized V 2 O 5 -rGO nanocomposite and used it to study the photocatalytic degradation of rhodamine B [ 16 ]. Sharma et al prepared V 2 O 5 /GO nanocomposite by a hydrothermal route and studied MB degradation and photoelectrochemical water splitting [ 11 ]. Therefore, V 2 O 5 /RGO composite may provide a new generation of material with excellent photocatalytic activity.…”

Visible-Light-Driven Photocatalytic Degradation of Tetracycline Using Heterostructured Cu2O–TiO2Nanotubes, Kinetics, and Toxicity Evaluation of Degraded Products on Cell Lines

“… 38 , 39 The efficiency of the semiconductor-based photocatalyst was enhanced with doping, heterogeneous composition, noble metal deposition, use of supportive materials, use of hybrid nanomaterials, and surface modification of the photocatalyst by using an alternative method of synthesis. 37 , 40 − 50 …”

“…TiO 2 is the most studied and used photocatalyst for the removal of antibiotics from wastewater. However, the large band gap limits the photoabsorbance in visible light and is a hindrance to the exploitation of the energetic potential for degradation and removal of antibiotics from wastewater. , The efficiency of the semiconductor-based photocatalyst was enhanced with doping, heterogeneous composition, noble metal deposition, use of supportive materials, use of hybrid nanomaterials, and surface modification of the photocatalyst by using an alternative method of synthesis. ,− …”
