description The invention provides a magnesium secondary battery positive electrode material MXene-Ti3C2/TiS2 and a preparation method thereof. According to the material, with a two-dimensional material MXene-Ti3C2 as a substrate, TiS2 with a layered structure is supported in a MXene-Ti3C2 sheet. Compared with the prior art, the magnesium secondary battery positive electrode material MXene-Ti3C2/TiS2 and thepreparation method have the advantages that the TiS2 is supported in the MXene-Ti3C2 sheet, and a supportable channel is established for embedding and ejecting magnesium ions. Compared with an existing magnesium secondary battery positive electrode material, the magnesium secondary battery positive electrode material of the invention has the advantages that the charge and discharge capacity is higher for 15% to 25%, the cycle performance is also greatly improved, and the coulombic efficiency is close to 100%. 一种镁二次电池正极材料MXene-TiC/TiS及其制备方法，是以二维材料MXene-TiC为基底，层状结构的TiS负载在MXene-TiC片层之中。与现有的技术相比，本发明的有益效果是：本发明一种镁二次电池正极材料MX
