The invention discloses an MIL-101 material with high water stability and a preparation method of the MIL-101 material. According to the method, transition metal ions such as Co<2+>, Ni<2+>, Cu<2+>, Zn<2+> and the like are introduced to serve as doping metal during coordination of organic ligand and metal, and form competition coordination with metal ions such as Fe<3+>, Cr<3+> and Al<3+>, organicacids such as citric acid, acetic acid and tartaric acid are added to serve as doping accelerators and play a role of a mineralizer, the transition metal ion doped bi-metal MIL-101 material is synthesized and washed, a coordination defect structure is removed by an acid solution with pH of 2-5, and the stable bi-metal MIL-101 material is obtained after drying. The method is green and simple, andthe synthesized bi-metal MIL-101 material has remarkably improved stability in water and has good synthesis repeatability. 本发明公开了一种高水稳定性的MIL-101材料及其制备方法。所述方法通过在有机配体与金属配位时引入过渡金属离子（如Co、Ni、Cu、Zn等）作为掺杂金属，与金属离子（Fe、Cr、Al）形成竞争配位，并加入有
