Sonocatalytic degradation of a textile organic dye over the novel zeolite Y/NiTiO۳ nanocomposite catalyst from water media

The present research was carried out to ultrasonic-assisted hydrothermal fabricate zeolite Y/NiTiO۳ nanocomposite for sonocatalysis of methylene blue (MB) from water media. The achieved outcomes of FESEM, EDAX, FTIR, XRD, and VSM analyses affirmed proper fabricate of zeolite Y/NiTiO۳ nanocomposite displayed the highest sonocatalytic degradation efficiency of ۹۸.۹% at irradiation time of ۳۰ min in the presence of the ultrasonic (US)/H۲O۲ system. The impacts of sonocatalyst amount and initial MB concentration on the degradation efficiency were investigated.Additionally, •OH radicals as the main reactive species during the sonodegradation reaction were distinguished. The degradation efficiency decreased only ۶% after ۴ repeated cycles. Therefore, zeolite Y/NiTiO۳ nanocomposite can be utilized as a promising sonocatalyst for the removal of organic dye contaminants with great reproducibility potential.
