Anatase TiO 2 sheets with exposed high‐energy (001) facets are grown on carbon fibers (CFs) by a facile hydrothermal synthetic route. The percentage of reactive facets in the TiO 2 nanosheets (NSs) is calculated to vary between about 40% and 92%, depending on the synthesis conditions. In comparison with TiO 2 NSs grown on a planar substrate, the TiO 2 NS/CF hybrid structure exhibits a 3.38‐fold improvement in photocatalytic degradation of methyl orange under UV‐light irradiation.
