16871 High Energy Ball Milling For Laboratory

Ball Mill

The binding energy of O1s in the range of 530.20532.30 eV and 533.20534.80 eV was allocated to oxygen vacancies and the oxygen that adsorbed on the surface or the hydroxyl ion groups respectively as depicted in Figure 3c which displays the doublet located binding energies at 159.20 and 164.80 eV correspond to the core lines of Bi4
