| description | TiO<sub>2</sub> nanomaterials have many disadvantages,including high photo-generated electron-hole recombination rate, low electron mobility, poor electrical conductivity and low reversible capacity, which have restricted application in the fields of photocatalysis and electrochemistry. MXene (M<sub><i>n</i>+1</sub>X<sub><i>n</i></sub>T<sub><i>x</i></sub>), a new type of two-dimensional transition metal carbides, nitrides, or carbonitrides, has a unique two-dimensional layer structure, excellent electrical conductivity, and high carrier mobility. By introducing MXene into TiO<sub>2</sub> nanomaterials to construct the TiO<sub>2</sub>/MXene nanocomposites, the synergistic effect of MXene and TiO<sub>2</sub> can further improve photocatalysis and electrochemistry properties. From the perspective of TiO<sub>2</sub> nanomaterials, the latest research progress on the controllable preparation, structural properties, applications in photocatalysis and electrochemistry of zero-dimensional, one-dimensional, and two-dimensional TiO<sub>2</sub> with MXene nanocomposites were reviewed. In particular, the construction mechanism of namocomposites and the enhancement mechanism of photocatalysis and electrochemistry properties of TiO<sub>2</sub> by MXene were emphasized. The shortcomings of the existing research on preparation of TiO<sub>2</sub>/MXene composites and its applications in photocatalysis and electrochemistry were analyzed.Furthermore,the future research directions of TiO<sub>2</sub>/MXene composites from the aspects of optimizing the preparation process,improving the properties and exploring the property enhancement mechanism were also prospected. |
