Ordered mesoporous materials have been widely used due to their properties such as high specific surface area, uniform pore diameter, large pore volume and stability for recyclability as electrode materials. In addition, transition metal oxides (TMOs), especially binary and ternary TMOs are promising materials for a range of potential applications in catalysis, chemical sensing, adsorption, separation and energy conversion and storage; lithium ion batteries, and supercapacitors due to their higher reversible capacity and better structural stability than single metal oxides. Among TMOs, copper oxide (CuO) is one of the attracting materials owing to its high theoretical capacity as an electrode, abundance, environmental friendliness, nontoxicity, and inexpensiveness. Therefore, expecting the synergistic effects of mesoporous CuO and TMOs, we synthesized several mesoporous mixed metal oxides (MMOs) based on CuO. In a hard templating method, the cubic Ia3d mesoporous silica KIT-6 was prepared to synthesize ordered mesoporous CuO and CuO-based MMOs. The materials are characterized by powder X-ray Diffraction, N2 adsorption-desorption isotherm analysis, scanning electron microscopy. |
