Abstract:

Monometallic Ce, Cu and bimetallic Ce-Cu was successfully synthesized at room temperature using silica rice husk (RH) via sol-gel route and were characterized through several physicochemical techniques such as N₂ adsorption-desorption, XRD and DR/UV-Vis analyses. The prepared materials were designated as RH-10Cu, RH-20Ce and RH-10Cu20Ce. High mesoporosity with Type IV characteristics were evidenced for all the materials. The BET surface area registered for RH-10Cu, RH-20Ce and RH-10Cu20Ce were 396.02, 245.54 and 194.87 m²g^-1 respectively. Well-dispersion of metal species was clearly evidenced from XRD analysis. The strong interaction between ceria and copper was observed over RH-10Cu20Ce through DR/UV-Vis analysis.
