Herein, TiO2/Al(H2PO4)(3) composite film was synthesized via a spray method. The composite film exhibited higher photocatalytic activity compared with pure TiO2 (about 1.4-fold). TiO2 nanoparticles were fixed on the framework of Al(H2PO4)(3), which could prevent the agglomeration of TiO2 nanoparticles and increase the reactive sites. More than that, the composite film was separation-free and bears good washing resistance thanks to the good adhesive force of Al(H2PO4)(3). The good adhesive force could be ascribed to the formation of Ti O P bond between TiO2 and Al(H2PO4)(3), which also contributed to the increased photocatalytic activity. This work presents a feasible method of fabricating TiO2-based separation-free and washing-resistance film, which may hold potential applications in the field of self-clean. (C) 2016 Elsevier B.V.
