Dimensional matched ultrathin BiVO4/Ti3C2Tx heterosystem for efficient photocatalytic conversion of CO2 to methanol
2022
Abstract Dimensional matched ultrathin BiVO4/Ti3C2Tx MXene 2D/2D heterosystem is developed via a facile electrostatic self-assembly process. The composite shows an increased CO2 uptake capacity than that of the bare BiVO4 nanosheets. Besides, the well collaborated 2D/2D heterogeneous structure efficiently promotes the photoexcited charge transfer and separation. As a result, the photocatalytic CH3OH production rate of the BiVO4/Ti3C2Tx hydrid can reach 20.13 μmol g−1h−1, which is 4.1 times of the pristine BiVO4.
