CuC₂O₄ porous spheres were prepared on a large scale by a mild aqueous solution method at 100℃ for 10 h with CuCl₂ and H₂ C₂ O₄ as raw materials.Structures and morphologies of as-products were characterized by X-ray powder diffraction(XRD) and scanning electron microscopy(SEM).The influences of experimental conditions such as the concentration of reactants,reactive temperature and the size of anions on the structures and morphologies of as-products were investigated.The results show that as-products were monoclinic structural CuC₂O₄ porous spheres with a diameter of 400~540 nm.Each porous sphere was made of many nanoparticles with a size of 50~80 nm.Reaction temperature had more effect on the size of CuC₂O₄ porous spheres.The concentrations of reactants and the volume of anions affect the size of the aggregates of particles.So through tuning the experimental conditions,CuC₂O₄ porous spheres could be controlled-synthesized.The formation mechanism of CuC₂O₄ porous spheres based on an etching effect was discussed.
