摘　　要：Nano-CuO was prepared by heating nano-Cu2(OH)2CO3 precursors in different calcination temperatures. The precursor was synthesized from water-alcohol mixed solution of Cu(Ac)2 using mixed solution of NaOH and Na2CO3 as precipitants. XRD, FT-IR, TEM, TG-DTA and surface area measurement techniques were used to investigate the properties of the CuO powder. The results show that the spherical, well dispersed nano-CuO powder with the average size of 15 nm and higher catalytic activity for H2O2 decomposition was obtained at 300 ℃. With the increasing of calcination temperature, crystal of CuO grows up, agglomeration of the powder becomes heavier and catalytic activity decreases. FT-IR patterns revealed that the vibration fine structure of Cu-O bond in nano-CuO powder disappears and main absorption is red-shifted with the average size of nano-CuO reducing.
