TiO 2 /C composite have been widely used in photoelectrochemistry and electrochemistry. Herein, we report a simple and ultrafast approach to produce TiO 2 /C nanocomposite. Multilayered Ti 3 C 2 T x , i. e. MXenes material, was oxidized into TiO 2 /C nanocomposite under microwave irradiation in 20 seconds. The resulting TiO 2 /C nanocomposite have a multilayer carbon structure and the TiO 2 crystals are embedded in the carbon layer. The interlayered TiO 2 could effectively prevent the restacking of carbon flakes. As an electrode material, the special structure of TiO 2 /C can increase the diffusion channel of ions and improve the transmission of electrons. Therefore, the TiO 2 /C nanocomposite exhibit good cycle stability. The TiO 2 /C nanocomposite are expected to be used for other electrode materials, such as lithium‐ion batteries, lithium‐sulfur batteries and photoelectrocatalysis devices.
