Notes:
Cu oxide nano powders were synthesized by the levitational gas condensation (LGC)method, and heated at temperature ranges from 150 to 450 [removed info]C. The nano powders consist of mainlyCu2O with an average size of 35 nm. The analysis of the IR-spectra of the nanopowders demonstratesthat the surface of the sample under an air exposure is coated by hydroxylhydride (-OH, H2O) andhydroxycarbonated [Cu2(OH)2CO3]. The change of the particle size by heat treatment below 450 °C isrelatively small. The variation of the adsorption ability is mainly defined under heating at least up to300 °C, by the surface state of the particles. The catalytic effect was increased at heat treated samples
