Abstract: (5175 Views)
In this paper nanoparticles of lithium-cobalt oxide on alumina and silica substrates, by sol-gel method and with citric acid as gelling agent were prepared. The effects of different substrates on size, shape and catalytic effects of nanoparticles were studied. To evaluate the catalytic activity, rate of decomposition of hydrogen peroxide in the presence of any of the samples by measuring the volume of oxygen gas released at the time, was investigated. The X-ray diffraction patterns (XRD), scanning electron microscopy (SEM) and FT-IR spectra confirmed the formation of Co3O4 and LiCoO2 phases
