Urchin-like NiO superstructures have been prepared via a thermal decomposition reaction of NiC2O4 at 400 degrees C for 1h. The morphology and structure of the synthesized urchin-like superstructures have been characterized by X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy. The results show that urchin-like NiO superstructures were a polycrystal with cubic structure and typical diameters of 200 to 500nm and the self-assembly nanoparticles average diameter is 14nm. The as-prepared NiO superstructures have a high Brunauer-Emmett-Teller surface area of about 60.32 m(2)/g. The UV-vis spectrum of urchin-like NiO consists of one peak at 357 nm (3.47 eV).
