Synthesis of graphene /CuGaO2 aerogels for advanced electrodes
Inorganic aerogels [1] are most often produced from silica, undergoing multiple phases of cooling and heating under high pressure (supercritical drying) or vacuum (lyophilization). Nowadays, low-cost organic aerogels such as graphene/metal oxide hydrogels are widely used in various applications (sup...

| Tartalmi kivonat: | Inorganic aerogels [1] are most often produced from silica, undergoing multiple phases of cooling and heating under high pressure (supercritical drying) or vacuum (lyophilization). Nowadays, low-cost organic aerogels such as graphene/metal oxide hydrogels are widely used in various applications (supercapacitors, oil absorption etc.) and fields like electronics, material science and aerospace engineering [2,3]. These carbon-based nanomaterials, having a nonpolar carbon structure, are useful especially for their essential hydrophobic properties [4], ultralow density, high surface area and high conductivity. Our previous work [5,6] included studies upon p-CuGaO2 dye-sensitized solar cells which revealed excellent optical transparency of CuGaO2. Also, CuGaO2 can be used in photocatalysis for the oxidation of hydrogen sulfide, while graphene can conduct the electrons generated in the conduction band of the semiconductor to the counter-electrode closing the electrical circuit. Hybrid materials like CuGaO2/graphene aerogels could be efficient for dyesensitized solar cells and advanced electrodes fabrication. |
