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 %> http://jsci.khu.ac.ir/article-1-1456-en.pdf %P 109-116 %& 109 %! the effect of diffrent beds on size and catalytic properties of cobalt oxide nanoparticles dopped with Li %9 Research Paper %L A-10-437-1 %+ %G eng %@ %[ 2011
