Mesoporous CuO/ZrO2 nanocatalysts: synthesis, characterization and low-temperature CO oxidation activities
Source abstract
Abstract
Mesoporous ZrO2 was synthesized by a simple surfactant-assisted method in the presence of the cationic surfactant cetyltrimethylammonium bromide, and the CuO loaded catalysts CuO/ZrO2 were prepared by a deposition–precipitation method. The obtained products were characterized by means of powder X-ray diffraction, N2-sorption, transmission electron microscopy (TEM), hydrogen temperature-programmed reduction and X-ray Photoelectron Spectroscopy techniques. Their catalytic performance for low-temperature CO oxidation was studied by using a microreactor-GC system. TEM and N2-sorption results showed that the obtained materials possess a mesoporous structure with high-surface area and uniform pore-size distribution. The results of catalytic activity tests revealed that these mesoporous nanostructured CuO/ZrO2 catalysts were very active for low-temperature CO oxidation.
