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 ).…”

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.…”

A hydrangea-like nitrogen-doped ZnO/BiOI nanocomposite for photocatalytic degradation of tetracycline hydrochloride

“…27,28 Nevertheless, ZnO, as a wide bandgap semiconductor (∼3.20 eV), has a narrow photoresponse range and responds mainly to UV light, which limits its application. [29][30][31] To overcome this limitation, some researchers found that carbon materials could promote photoelectronic transformation because their excellent electron conductivity can facilitate the efficient utilization of spatial charge carriers. 21,32,33 Meanwhile, metal-organic frameworks (MOFs), a porous substance created by the self-assembly of metal ions or clusters and organic linkers, have attracted a lot of interest in a number of domains, including photocatalysis.…”
