Photocatalysis is excellent for water treatment, but its efficiency is often limited by the quick recombination of photoinduced electron-hole pairs. Two-dimensional titanium carbide (Ti3C2Tx) MXene has become a promising photocatalyst for improving wastewater treatment efficiency, thanks to its excellent light absorption and charge separation properties. In this study, the photocatalytic behavior of Ti3C2-MXene, which is partially modified with TiO2 photocatalysts, is investigated. The results of Mxene’s phase analysis proved that in addition to the complete removal of aluminum, it contains TiO2, which enhances the photocatalytic performance of MXene. Under visible light, the synthesized MXene containing TiO2 demonstrated superior performance in degrading methylene blue compared to P25. With this photocatalyst, the methylene blue degradation efficiency reached 49.60 % within 4 h. The junction between Ti3C2 and TiO2 facilitated the generation of electron-hole pairs and prevents their recombination. The effect of pollutant pH was such that with its increase, photocatalytic degradation increased. Also, a proposed photocatalytic mechanism emerged from the findings of the Mott–Schottky analysis, Tauc plot, .and scavenging tests
