Enhanced photocatalytic activity of ZnO nanoparticles by surface modification with KF using thermal shock method

Super-hydrophobic and photocatalytic antimicrobial activity of iodine-doped ZnO nanoarray films

“…The two main peaks located at 1021.4 (Zn 2p 3/2 ) and 1044.5 eV (Zn 2p 3/2 ) in the Zn 2P spectrum are attributed to Zn 2+ in the ZnO lattice. 14 In the O 1 S high resolution XPS spectrum, the three peaks at 530.1, 531.6 and 532.1 eV correspond to the lattice oxygen O 2À (O L ) in ZnO, oxygen defect (O D ) in the lattice and hydroxyl oxygen (O H ). 14,15 These results suggested that the doped iodine in the zinc oxide generated oxygen defects in the ZnO lattice.…”

Efficient photocatalytic degradation of dyes using photo-deposited Ag nanoparticles on ZnO structures: simple morphological control of ZnO

“…However, the efficiency of ZnO is still limited due to the rapid recombination of electron-hole pairs, 12,13 and the activity in the visible region is considerably lower than that in the ultraviolet region. 15,16 In photocatalytic reactions, the morphology of the catalyst can dramatically affect the properties and performance of the catalyst. A considerable number of morphology-controlled TiO 2 photocatalysts have been developed with various designs, including spheres, nanosheets, nanotubes, 3-D sea urchin-like, and 3-D hierarchically porous structures; these photocatalysts have been proposed and utilized in photocatalytic air purication.…”

One Step In-Situ Synthesis of Zinc Oxide Nanoparticles for Multifunctional Cotton Fabrics

“…The extraordinary photo catalytic properties due to the electronic structure of ZnO nanoparticles also empower them to be used as degradation reagents for various types of pollutants; e.g., it can be used in the textile industry for dyes and surfactants degradation in the waste water. ZnO is made of Zn 2+ and O 2+ ions that are bonded with each other with a considerable extent of ionicity and with a minor degree of covalency [ 16 , 22 , 23 , 24 , 25 , 26 , 27 ].…”
