Significance of Ni doping on structure-morphology-photoluminescence, optical and photocatalytic activity of CBD grown ZnO nanowires for opto-photocatalyst applications

The photocatalytic degradation of a binary textile dyes mixture within a new configuration of loop reactor using ZnO thin film-phytotoxicity control

“…The average crystallite size (D) of the nanostructures calculated based on Scherrer's equation is 27.04 nm and 11.94 nm for ZnO deposited by "Spray" and "Spray Pyrolysis" respectively. The obtained values of the average particle size (D) are smaller than those reported in the literature [27,31,34,35].…”

Efficient Ni and Fe doping process in ZnO with enhanced photocatalytic activity: A theoretical and experimental investigation

“…For instance, the presence of Fe 3+ ions decreases the number of V o and O i ions compared to undoped ZnO due to the formation of local defects represented by one cation vacancy (V " Zn ) every two Fe 3+ dopant ions in order to charge balance [56]. Upon Ni 2+ incorporation, the intensity of PL emission also increases because of distortion centers in the ZnO lattice resulting from the presence of [NiO 6 ] clusters [60]. The interaction between the dopant ions and the host semiconductor contributes to the separation of electron-hole pairs, which can be subsequently related to their photocatalytic activity [61].…”

EFFECT OF ADDITIONAL Ni METAL DOPANTS ON OPTICAL ABSORPTION PROPERTIES AND CRYSTAL STRUCTURE OF ZnO PHOTOCATALYST MATERIALS

“…This indicates a distortion in the lattice caused by the presence of amorphous NiO and/or the presence of segregation of Ni atoms at grain boundaries. 20 The presence of NiO also affects the size of the lattice parameters.…”
