Magnéli phase titanium suboxides (M-TSOs) belong to a type of sub-stoichiometric titanium oxides based on the crystal structure of rutile TiO. They possess a unique shear structure, granting them exceptional electrical conductivity and corrosion resistance. These two advantages are crucial for electrode materials in electrochemistry, hence the significant interest from numerous researchers. However, the preparation of M-TSOs is uneconomic due to high temperature reduction and other complex synthesis process, thus limiting their practical application in electrochemical fields. This review delves into the crystal structure, properties, and synthesis methods of M-TSOs, and touches on their applications as electrocatalysts in wastewater treatment and electrochemical water splitting. Furthermore, it highlights the research challenges and potential future research directions in M-TSOs.
马格内利相低价钛氧化物（M-TSOs）属于一类基于金红石TiO晶体结构的非化学计量比钛氧化物。它们具有独特的剪切结构，赋予它们卓越的导电性和耐腐蚀性。这两个优点对于电化学中的电极材料至关重要，因此引起了众多研究人员的极大兴趣。然而，由于高温还原和其他复杂的合成过程，M-TSOs的制备不经济，从而限制了它们在电化学领域的实际应用。本文综述深入探讨了M-TSOs的晶体结构、性质和合成方法，并涉及它们作为电催化剂在废水处理和电化学水分解中的应用。此外，它还强调了M-TSOs的研究挑战和未来潜在的研究方向。
