Abstract
Thulium titanate/polyaniline nanocomposites were synthesized to observe the
sonophotocatalytic degradation of dyes (widely used as a model pollutant) under ultrasonic
irradiation and visible light. Based on our results, the synthesis process can improve sol-gel
assisted sonochemical method in the presence of ultrasound and starch. To prepare pure
thulium titanate nanostructures, the presence of starch and sonication treatment were
concurrently obligatory. Therefore, sol-gel assisted sonochemical method can be used as a
successful process for synthesis of thulium titanate nanostructures. According to the BET
results, in the presence of ultrasound and starch surface area increased from 9.5305 m2/g to
40.28 m2/g. For verification of photacatalytic behavior of nanoparticles, several factors were
studied. The nanocomposites/ultrasonic system showed greater photocatalytic activity for the
degradation of Rh B rather than separately treatment of nanocomposites under visible light.
