But the research on the activation of ball milling in the preparation of nanocomposites was rarely mentioned. Inspired by this, the ball milling process was used to generate active sites on the surface of ZrO 2, and was combined with the pyrolysis method, so the ball milling-pyrolysis method for NiOZrO 2 nanocomposite preparation was proposed.
The mechanical method is a processing way for breaking a metal into a powder of the desired particle size by means of a mechanical external force, and the chemical composition of the material in the preparation process is substantially unchanged. The currently widely used methods are ball milling and grinding, which have the advantages of ...

May 04, 2020 The wet ball milling WBM method is, for the first time, used for the exfoliation of bulk black phosphorus BP to obtain few-layer black phosphorus FBP. Before that, the rational solidliquid ratio of raw material is determined to be 11 mgmL for the popular ultrasound liquid exfoliation ULE. Obviously, the high proportion of organic solvent used in ULE will lead to serious ...
May 13, 2019 Nickel acetate tetrahydrate NiCH3COO2 4H2O was used as a precursor to prepare reduced graphene oxide decorated with Ni nanoparticles Ni-rGO by a ball millingthermal decomposition method. Ni-rGO was characterized by scanning electron microscopy, transmission electron microscopy, x-ray diffraction analysis, Fourier-transform infrared spectroscopy, and Raman
Apr 28, 2019 Graphene nanoplatelets were successfully prepared from graphite powder by simple and scalable thermal shock combined with ball milling methods. The formation of the graphene nanoplatelets were observed by field-emission scanning electron microscopes and BrunauerEmmettTeller methods with the much smaller number of layers and the considerable
