Nano-CuCo_2O_4 was prepared by salt-assisted solution combustion method using copper nitrate and cobalt nitrate as raw materials,urea as ignition and combustion agent.The prepared nano-CuCo_2O_4 was characterized by X-ray diffractometry(XRD),transmission electron microscopy(TEM),Fourier transform infrared spectroscopy(FTIR) and Laser Raman Spectroscopy(LRS).The results showed that the CuCo_2O_4 particles are almost cubic-like shaped,and the sizes are about 50nm with a good dispersion.The catalysis activity ...
