description | The article presents the results of comparative research on the physicochemical characteristics and catalytic activity of copper oxide supported on synthetic SiO<sub>2</sub> and SiO<sub>2</sub> (RH) from rice husk. SiO<sub>2</sub> (RH) is more hydrophobic compared to SiO<sub>2</sub>, which leads to the concentration of copper oxide on its surface in the form of a “crust”, which is very important in the synthesis of low-percentage catalysts. According to SEM, XRD, and TPR-H<sub>2</sub>, the use of SiO<sub>2</sub> (RH) as a carrier leads to an increase in the dispersion of copper oxide particles, which is the active center of ethanol dehydrogenation. |
