Fabrication TiO 2 with conductive two-dimensional materials is an effective strategy to improve its photocatalytic activity. Herein, a well-de ned carbon doped TiO 2 /Ti 3 C 2 heterojucntion is constructed via in-situ controllable oxidation of Ti 3 C 2 MXene in carbon dioxide. The formed carbon doped TiO 2 nanoparticles as the photocatalyst uniformly disperse on the surface of Ti 3 C 2 MXene and generate electrons and holes under the irradiation. The twodimensional Ti 3 C 2 MXene, ascribing to its excellent conductivity, acts as the electron transport channels and accelerates the separation of photo-generated electrons and holes. Meanwhile, due to its large speci c surface area and good solubility, Ti 3 C 2 MXene may facilitate to enhance the adsorption of pollutant on the photocatalyst as well as the absorption of photocatalyst for visible light. Therefore, the unique properties of TiO 2 and Ti 3 C 2 MXene are integrated in a complementary way and signi cantly improve the photocatalytic performance of the composites.The proper content of Ti 3 C 2 MXene and TiO 2 in the composite is crucial for enhancing the photocatalytic performance, which can be effectively tuned by varying the oxidation temperature. In this work, C-TiO 2 /Ti 3 C 2 oxidized at 400 o C presents the optimum photocatalytic performance.
