Solar photocatalytic degradation of organic pollutants in textile industry wastewater by ZnO/pumice composite photocatalyst

Fly ash-, foundry sand-, clay-, and pumice-based metal oxide nanocomposites as green photocatalysts

“…158,165 Recent studies indicated pumice is a potential support material for metal oxides by enhancing the oxidation capacity or reducing the treatment time. 65,[126][127][128]166 A unique skeleton structure containing numerous empty pores with a large surface area and surface chemical activity of pumice are the driving forces behind this enhancement.…”

“…Chemical compositions of the natural pumice from different locations Unported Licence.polycarbonate as the substrate to x pumice stone pellets, as compared to that of other supports such as inorganic bres, organic bres, and polyacrylonitrile.Recently, Yusuff et al128 successfully obtained ZnO-pumice composite via an incipient impregnation method for degradation of organic pollutants in textile industry under sunlight irradiation. ZnO-pumice composite exhibited a large specic surface area of 122.81 (m 2 g À1 ) and an improved photocatalytic performance of 90.17%.…”

Photocatalytic properties of Cu-containing ZnO nanoparticles and their antifungal activity against agriculture-pathogenic fungus

“…The degradation data for the evaluated NPs follow first-order kinetics, which has been used to describe the degradation of various pollutants by ZnO-based photocatalysts (see Table 3 ). 45 The highest degradation was found for ZnO/Cu 2% NPs, with nearly 90% degradation of MO in 100 min. The high photocatalytic activity of the ZnO/Cu 2% NPs is attributable to the Cu dopant incorporated in ZnO, which widens the absorption band as shown in Fig.…”

Photocatalytic Activity of Cu2S/WO3 and Cu2S/SnO2 Heterostructures for Indoor Air Treatment

“…Composite materials (graphene/ZnO, textiles/TiO 2 , fly ash/semiconductors, etc.) combine both photocatalytic and absorbance processes and usually exhibit high removal efficiencies [22][23][24]. The main issue is related with the incomplete decomposition of the absorbed pollutant, which has the potential to be released in the environment.…”
