TiO 2 nanosheets with dominant {001} facets, coupled with Cs 2.5 H 0.5 PW 12 O 40 , were successfully synthesized by a one‐step hydrothermal reaction. The photocatalytic activity of nanocatalysts was evaluated by the degradation of Rhodamine B under UV light irradiation. The results showed that both the addition of Cs 2.5 H 0.5 PW 12 O 40 and the exposed {001} facets of TiO 2 have a positive effect on the photocatalytic activity. The improved photoactivity of nanocomposites in comparison with that of TiO 2 nanosheets could be attributed to the synergistic effect between Cs 2.5 H 0.5 PW 12 O 40 and TiO 2 which facilitates the separation of photo‐induced hole‐electron pairs.
