TiO2/Ti3C2Tx composites were synthesized by a solvothermal method with Ti3C2Tx as substrate and isopropanol (C3H8O) as an inducer. The phase composition and microstructure of TiO2/Ti3C2Tx were characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy and ultraviolet-visible diffuse reflectance spectroscopy. The results show that anatase type TiO2 is uniformly grown on the layered surface of Ti3C2Tx, thus improving the electron transport performance of TiO2/Ti3C2Tx composites. The optimum photocatalytic performance of TiO2/Ti3C2Tx-24 h can be obtained under the irradiation of 500 W mercury lamp (365 nm UV light), and the degradation efficiency of methyl orange (MO) is 95% for 75 min, which is 67.7% greater than that of pure TiO2 photocatalyst.
