Ball-milling synthesized hydrotalcite supported Cu

A rapid solvent-free ball-milling method was developed to prepare a hydrophobic hydrotalcite supported CuMn mixed oxide catalyst (CuMn/HT). The mechanochemically prepared catalyst exhibited high catalytic activity and recyclability towards the aerobic synthesis of 2-acylbenzothiazoles and quinoxalines in green medium ethanol compared with the ones synthesized via grinding and wet

Preparation of Black Phosphorus by the Mechanical Ball

In this paper, red phosphorus successfully turned to black phosphorus by the mechanical ball milling method. The samples were analyzed by the X-ray diffraction (XRD) method and by high resolution transmission electron microscopy (HRTEM). The XRD result showed that the black phosphorus obtained had small crystal size and a small, amorphous, broadly diffused peak of red phosphorus.
