| 제목 | A Green and Facile Route for Preparing Graphene/TiO2/Ag Nanocomposite Aerogel with Improved Adsorption Capacity and Photocatalytic Activity |
| 초록 | Graphene-based 3D macrostructures are electrically conductive, mechanically strong and thermally stable. On the other hand, TiO2 displaying unique optical and electronic properties, has been widely employed in the area of sustainable energy and environmental remediation. Here, we reported a green and facile route for preparing graphene/TiO2 and graphene/TiO2/Ag nanocomposite aerogel. Graphene oxide nanosheets are first in situ deposited with TiO2 nanoparticles, then Ag nanoparticles are decorated on the surface to improve quantum yield. The hybrid is assembled to be a bulk gel by a mild chemical reduction, followed by supercritical CO2 dryingThe application of them for photocatalytic degradation of MB under UV and visible light has been investigated.
