文摘
- •
CO2 photoreduction was conducted over graphene oxide/oxygen-rich TiO2 under visible light.
- •
Process parameters such as light intensity as well as CO2 and H2O partial pressures were studied.
- •
A methane yield of 3.45 μmol gcat−1 was obtained at the most suitable process conditions.
- •
Kinetic studies of CO2 photoreduction over graphene oxide/oxygen-rich TiO2 were presented.
- •
The experimental data was successfully fitted into a dual-site Langmuir-Hinshelwood model.
