In the present study, a series of ferroelectricsLi1-xTa1-xWxO3materials have been prepared by a solid-state process, characterized by using XRD, UV−vis spectroscopy and SEM, and then tested as new photocatalysts for the degradation of Methylene Blue (MB) in dye solution. The X-ray diffraction reveals a rhombohedra structure for all compositions from x = 0.00 to x = 0.25 which is the limit value. The photo-catalytic performance was evaluated through degradation of Methylene blue dye with ferroelectricmaterials. The best results in terms of photodegradation were obtained with x = 0.10, 0.20 and 0.25; more specifically, the initial degradation rate of methylene blue was four times higher than with the x = 0.00.
