Dispersion of CoCl2 into γ-Al2O3 studied by positron


Co2+/γ-Al2O3 samples were prepared by incipient wetness impregnation of γ-Al2O3 with different concentration solution of CoCl2 and dried at 40 °C. We measured the positron lifetime spectra of the samples of different Co2+ mass fractions (0%–8.24%) heated at different temperatures (100–500°C). All lifetime spectra were resolved into four components, in which… (More)
