The perovskite structure NaLaTi2 O6 were prepared by using Ti (SO4 )2 and La(NO3 )3 as raw material ,ethanol‐water solution as solvent via the solvothermal method . The phase compositions and morphology of samples were characterized by X‐ray diffraction (XRD) and scanning electron microscopy (SEM ) .It is researched that the effects of different volume ratio of ethanol‐water solution on the morphology and photocatalytic activity of sam‐ples NaLaTi2 O6 .Results show that the NaLaTi2 O6 sample with two‐dimensional nanosheets has higher photocatalytic activity to degrade Methylene blue ,which degradation efficiency reaches 93% under UV irradiation for 30 min .
