摘要: Abstract This research deals with preparation, characterization and shape dependent performance of copper oxide nanomaterials (CuO NMs) in simple carbon monoxide (CO) oxidation catalysis. Uniform high purity rice grains-like, needle-like sheet-like CuO NMs were achieved by adopting different experimental conditions. The selective physically mixed re-pelletized γ-Al2O3 thus 1 wt% CuO/γ-Al2O3 catalyst was prepared. catalysts exhibited good surface area (186–190 m2 g−1), crystallinity, thermal stability metal dispersion. various CO catalysis showed that performed superior against grains-like or sheet like the temperature region between 200 225 °C. 100% CO2 formation at 325 400 °C dry wet Also, every process temperature, differences catalytic activity due to catalyst's could be noted significantly. It observed morphology played main role achieving efficient process.
