“…In previously reported work, the dye degradation performance of nickel and thorium codoped ZnO was studied for methylene blue (MB) dye which has shown 93% photocatalytic efficiency in 180 min at pH-10 . Dysprosium doped ZnO, prepared by a combustion method with the assistance of tartaric acid, displayed a MB degradation efficiency of 97% within 75 min . Cobalt (Co) and manganese (Mn) doped ZnO, synthesized by the coprecipitation method, had shown maximum photocatalytic performance for methyl orange (MO) at 12 wt % of Mn at pH value of 4 .…”

In this work, silver (Ag) doped zinc oxide (ZnO) nanoparticles were synthesized using zinc chloride, zinc nitrate, and zinc acetate precursors with (0 to 10) wt % Ag doping by a simple reflux chemical method. The nanoparticles were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, ultraviolet visible spectroscopy, and photoluminescence spectroscopy. The nanoparticles are studied as a photocatalyst for visible light driven annihilation of methylene blue and rose bengal dyes. The 5 wt % Ag doped ZnO displayed optimum photocatalytic activity toward methylene blue and rose bengal dye degradation at the rate of 13 × 10 −2 min −1 and 10 × 10 −2 min −1 , respectively. Here we report antifungal activity for the first time using Ag doped ZnO nanoparticles against Bipolaris sorokiniana, displaying 45% efficiency for 7 wt % Ag doped ZnO.

“…The obtained results are in good agreement with those found by S. Nguanprang et al for Dy-doped ZnO nanoparticles at 5% deposited by the combustion technique. 48 This increase in photocatalytic activity with the increase in doping can be explained by the inhibition of the recombination of photogenerated electron–hole pairs following the substitution of Zn 2+ by Dy 3+ . Indeed, the optical and morphological results confirm this enhancement, and the sample doped at 6% with Dy presents the lowest value of bandgap energy.…”

“…Among the semiconductors, ZnO has found application in removing various contaminants due to its nontoxic nature, low cost correlated with high photosensitivity, chemical and physical stability [ 1 , 2 , 3 ]. Despite its great qualities, ZnO has several deficiencies like the limit of UV-light adsorption due to the wide band gap, fast recombination of photo generated electron-hole pairs [ 4 ], and relatively poor electrical conductivity [ 5 ]. Therefore, it is necessary to combine it with other materials in order to improve its photocatalytic [ 6 ] and electrocatalytic activity [ 7 ].…”

N-doped graphene-ZnO hybrid materials with different N-doped graphene:ZnO wt% ratios (1:10; 1:20; 1:30) were prepared by a simple and inexpensive sol-gel method. The materials denoted NGr-ZnO-1 (1:10), NGr-ZnO-2 (1:20), and NGr-ZnO-3 (1:30) were investigated with advanced techniques and their morpho-structural, photocatalytic, and electrocatalytic properties were reported. Hence, pure N-doped graphene sample contains flakes with the size ranging from hundreds of nanometers to micrometers. In the case of all NGr-ZnO hybrid materials, the flakes appear heavily decorated with ZnO nanoparticles, having a cauliflower-like morphology. The X-ray powder diffraction (XRD) investigation of N-doped graphene sample revealed that it was formed by a mixture of graphene oxide, few-and multi-layer graphene. After the ZnO nanoparticles were attached to graphene, major diffraction peaks corresponding to crystalline planes of ZnO were seen. The qualitative and quantitative compositions of the samples were further evidenced by X-ray photoelectron spectroscopy (XPS). In addition, UV photoelectron spectroscopy (UPS) spectra allowed the determination of the ionization energy and valence band maxima. The energy band alignment of the hybrid materials was established by combining UV–Vis with UPS results. A high photocatalytic activity of NGr-ZnO samples against rhodamine B solution was observed. The associated reactive oxygen species (ROS) generation was monitored by electron paramagnetic resonance (EPR)-spin trapping technique. In accordance with bands alignment and identification of radical species, the photocatalytic mechanism was elucidated.
