Direct Precipitation Method of Nano-CuO

Different reaction conditions were studied through orthogonal experiment and single factor experiment. Using Cu(NO3)2 as the reactant, water-alcohol solution (H2O:CH2CH3OH was 3:1) as solvent at 20°C and reaction for 45min could get nano-CuO with good dispersion and uniform size. Different kinds of characterization method were used to characterize the resultant. The average diameter of nano-CuO was 20.38nm after calculated using some relevant formula, the surface area was about 21.988 m2/g, the pore diameter was about 3.079 nm and the pore volume was 1.349×10-1 cc/g . So the method is a feasible, low cost way to industry.
