Ultrathin two‐dimensional (2D) crystalline materials show high specific surface area (SA) of high energy (HE) facets, imparting a significant improvement in their performances. Herein we report a novel route to synthesize TiO 2 nanofilms (NFs) with atomic thickness (<2.0 nm) through a solvothermal reaction mediated by the hydrogen‐bonding networks constructed by hydroquinone (HQ). The resultant TiO 2 NFs have nearly 100 % exposed (001) facets and give an extremely high SA up to 487 m 2 g −1 . The synergistic effect of HQ and choline chloride plays a vital role in the formation of TiO 2 NFs and in the exposure of HE (001) facets. Because of its ultrathin feature and exposed (001) facet, the N 2 ‐annealled TiO 2 NFs showed fast kinetics of lithium insertion/extraction, demonstrating foreseeable applications in the energy storage.
