A Simple Ball Milling Method for the Preparation of p-CuO/n-ZnO Nanocomposite Photocatalysts with High Photocatalytic Activity
thesized by a simple ball-milling method. Micro-structure analysis shows that the nanoparticles are of single crystalline ZnO wurtzite structure. XRD, HRTEM, EDS, UV visible, and PL measurements indicate that Co2þ substitute into ZnO lattice at Zn2þ site, instead of forming impurity compound or cobalt oxide. The exchange interactions between
In addition, Castricum et al. report that the milling process of mixed Cu, Cu 2 O or CuO and ZnO in synthetic air results in oxidation of Cu precursors, while, under vacuum, it results in reduction. They also report that the mechanochemical reactions are promoted by mechanical milling in the presence of ZnO .
Apr 29, 2011· Nanoparticles of zinc oxide (ZnO) are increasingly recognized for their utility in biological applications. In this study, the high-energy ball milling (HEBM) technique was used to produce nanoparticles of ZnO from its microcrystalline powder. Four samples were ball milled for 2, 10, 20, and 50 hours, respectively.
