Influence of colloidal graphene oxide on photocatalytic activity of nanocrystalline TiO2 in gas-phase ethanol and benzene oxidation

- TiO2/graphene oxide serves as photocatalyst of ethanol and benzene vapors oxidation.
- 4-times acceleration of the photoprocesses is achieved with graphene oxide addition.
- Graphene oxide is much more active catalyst than graphite and graphite oxide.
- Photoreduction of graphene oxide decreases its catalytic activity.
