In this work, the titanium dioxide ([Formula: see text]) nanofilms co-doped with [Formula: see text] and [Formula: see text] ions were successfully fabricated by the sol–gel method with dip-coating process. Methylene blue was used as the target degradation chemical to study the photocatalytic properties affected by different doping contents of [Formula: see text] and [Formula: see text] ions. The samples were characterized by X-ray diffractometer (XRD), scanning electron microscopy (SEM) and infrared (IR) spectroscopy. The results indicated that both pure [Formula: see text] nanofilms and single-doped samples possessed the photocatalytic activity in degradation of methylene blue. However, when the nanofilms co-doped with [Formula: see text] and [Formula: see text] ions were fabricated at the molar ratio of 3:1 ([Formula: see text]:[Formula: see text]), they exhibited the best photocatalytic activity after the heat treatment at [Formula: see text]C for 2[Formula: see text]h. The wettability property test indicated that the [Formula: see text] nanofilms co-doped with [Formula: see text] and [Formula: see text] ions in the molar ratio 3:1 owned an excellent hydrophilic property.
