Photocatalytic behavior of ZnO and Pt-incorporated ZnO nanoparticles in phenol degradation

Solar photocatalytic decomposition of ethyl paraben in zinc oxide suspensions

“…This said, other semiconductors have also been tested for photocatalytic water remediation; of these, ZnO, whose band gap energy and photocatalytic mechanism are similar to that of TiO 2 [3], exhibits most of titania's beneficial features possibly with the exception of stability due to photo-corrosion [4]. In several cases, ZnO has shown comparable or even better performance than TiO 2 for the degradation of various contaminants [5][6][7][8][9][10].…”

Enhancing the photocatalytic activity of ZnO nanoparticles for efficient rhodamine B degradation by functionalised graphene nanoplatelets

“…Composite materials based on ZnO nanoparticles have been extensively explored to enhance ZnO efficiency in photocatalysis by loading with metal ions [2][3][4], coupling with other metal oxides [5][6][7] and combining with carbonaceous materials [8]. Graphene has shown outstanding performance in these applications due to its intrinsic electron delocalisation, which promotes electron transport between the composite photocatalyst and the pollutant molecules [9], and its excellent charge separation ability [10].…”

Photocatalytic degradation of 17α‐ethynylestradiol in environmental samples by ZnO under simulated solar radiation

“…Mechanistically, illumination of ZnO creates near or upon its surface electron-hole pairs as follows: 7,9 ZnO + hv → h…”

“…3 The photocatalytic mechanism of ZnO is similar to that of TiO 2 7,8 and it also exhibits most of its beneficial features (possibly with the exception of stability as will be discussed in detail). 9 In several cases, ZnO has shown comparable or even better performance than TiO 2 for the aqueous phase degradation 15,16 One of the fields to which semiconductor photocatalysis may successfully be applied is the removal of emerging microcontaminants from waters and wastewaters. Endocrine disrupting compounds (EDCs) constitute an important class of such contaminants, which pose an increasing threat to aquatic organisms, as well as to human health.…”
