CuO系粉体催化剂的制备方法及其分解H2O2活性研究

Copper(Ⅱ) oxides powder catalysts were prepared by three different methods,thermal decomposition,solid phase reaction and chemical precipitation.The phase,surface structure,morphology,particle size and catalytic activity of the powder for H 2O 2 decomposition were investigated by XRD,SEM,FT IR and the surface area measurement techniques.These studies revealed that high low sequence of catalytic activity of powder prepared by three different methods is opposite from their surface area,and that catalytic activity of the powder is principally related to its surface structure and active compositions.
