Photocatalytic degradation of phenol and benzoic acid using zinc oxide powders prepared by the sol–gel process

Sensitivity analysis of the photoactivity of Cu–TiO2/ZnO during advanced oxidation reaction by Adaptive Neuro-Fuzzy Selection Technique

“…It was attributed to the zero charge point of the catalyst which is defined as the point at which surface charge of the catalyst is null (pH PZC ). It has been reported that pH PZC is about 6.0 and 9.0 for TiO 2 and ZnO[26][27][28], respectively. Therefore, at pH>pH PZC , deprotonation reaction that takes place makes the catalyst surface negatively charged.…”

Synthesis, structural and optical properties of pure ZnO and Co doped ZnO nanoparticles prepared by the co-precipitation method

“…There are several methods reported in the literature for the synthesis of undoped, doped ZnO NPs and its derivatives which can be categorized into either (Chemical or Physical, co-precipitation, hydrothermal, solvothermal, emulsion and microemulsion methods etc.) [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Among the various methods, co-precipitation is one of the most important methods to prepare the nanoparticles.…”

Poly (Ethylene Glycol) (PEG)-assisted shape-controlled synthesis of one-dimensional ZnO nanorods

“…However, the absorption spectra of PEG capped ZnO showed that the absorption edges shift toward the higher wavelength, which originated from the localized surface modified phenomenon of PEG capped molecules loaded on the surface of ZnO [3]. These observations were carried out to determine optical band gap energies with the help of Kubelka-Munk equation [27]:…”
