Nano sheets, needles and grains-like CuO/γ-Al2O3 catalysts' performance in carbon monoxide oxidation

This research deals with the preparation, characterization and shape dependent performance of copper oxide nanomaterials (CuO NMs) in simple carbon monoxide (CO) oxidation catalysis. Uniform and high purity rice grains-like, needle-like and sheet-like CuO NMs were achieved by adopting different experimental conditions. The performance of various shape CuO/γ-Al2O3 catalysts in CO oxidation catalysis showed that needle-like CuO NMs performed superior against grains-like or sheet like CuO NMs in the temperature region between 200 and 225 °C. In every process temperature, differences in the catalytic activity due to catalyst's shape could be noted significantly.191
