Niobium‐doped Titanium dioxide ( Nb : TiO 2 ) transparent films were successfully deposited on glass substrates using a non‐aqueous sol‐gel spin coating technique. The effect of Nb concentration on the structural and photocatalytic properties of Nb : TiO 2 films was studied using X‐ray diffraction ( XRD ), scanning electron microscopy ( SEM ), atomic force microscopy ( AFM ), and UV visible spectroscopy. The films with 12 at.% (atomic percent) Nb doped TiO 2 showed excellent photocatalytic activity through 97.3% degradation of methylene blue ( MB ) after 2 h of UV irradiation.
