Green synthesis of multilayer Graphene/ZnO nanocomposite for photocatalytic applications

ZnO nanostructured matrix as nexus catalysts for the removal of emerging pollutants

“…Thus, the extract from crushed leaves of Ageratum houstonianum was brought into contact with Zn(NO 3 ) 2 ·6H 2 O solution, the precipitate formed being dried in an oven at 60 °C and calcined at 700 °C for obtaining crystalline ZnO NPs. In order to make the dye degradation process more efficient by irradiation with natural sunlight, NPs were anchored in multilayer graphene obtained from corn husk, thus obtaining nanocomposites with a crystallite size of about 40 nm (Sebuso et al 2022 ).…”

Unusual aliovalent Cd doped γ‐Bi2MoO6 nanomaterial for efficient photocatalytic degradation of sulfamethoxazole and rhodamine B under visible light irradiation

“…Photocatalysts should feature an appropriate band edge to generate free radicals, possess excellent visible light response characteristics, and absorb sufficient visible light to promote the catalytic degradation of pollutants. Currently, many scholars have carried out corresponding research on semiconductor materials such as TiO 2 , [10,11] ZnO, [12,13] SnO 2 , [14][15][16] BiOX (X = I, Cl, Br), [17][18][19] g-C 3 N n (n = 4 or 5), [20,21] MXene, [22] Lignin, [23] Bi 2 WO 6 , [24,25] and Bi 2 -MoO 6 , [26][27][28] which have been applied in the field of global water environment governance.…”

Eco-friendly multi-layered nanoswabs for sensitive removal of antibiotic-resistant bacteria from drinking water sources and their molecular biology studies

“…[8][9][10][11][12][13][14][15][16][17][18][19][20] Further, to improve the water purification level, membranes embedded with NMs are being investigated. [21][22][23][24] Many multi-layered and mixed-matrix membranes have been developed that show higher water permeability compared to solid NMs and conventional RO membranes. [22][23][24][25][26] Dikin et al have fabricated graphene oxide (GO) paper and reported that the thickness of pristine GO (0.34 nm) and empty spacing between the carbon atom layers (0.6 nm) were enough to accommodate a monolayer of water.…”
