Low-Temperature Catalytic Performance of Nanostructured CuO

摘要

We report the low temperature catalytic performance of nanostructured CuO fabricated at low temperature (50 degrees C) in the single step hydrothermal reaction between copper(II) acetate Cu(CH3COO)(2) center dot H2O and 2-piperidinemethanol (2PPM) in the absence of a template or structure-directing surfactants. The resulting nanostructured CuO (monoclinic space group C2/c; lattice constants: a = 0.5244 nm, b = 0.3799 nm, c = 0.5656 nm with beta = 100.8) possessed a dendritic morphology containing short nanorod-like substructures (diameter around 10 nm and average lengths of about 20-30 nm), and displayed a relatively large surface area (146 m(2) g(-1)). This novel nanostructured CuO material was demonstrated to selectively promote the NO-to-N-2 conversion at a relatively low temperature of 150 degrees C.
