. the sonocatalytic activity of nano-sized zno powder was studied via the degradation of the direct blue 71 azo dye. the nano-sized zno powder that was selected was the same as that which was synthesized and characterized in our previous study. the influences of six operational parameters including the initial ph, the initial concentration, the dose of sonocatalyst, the ultrasound frequency, th...

The novel ultrasound-assisted co-precipitation method was successfully applied for the synthesis of NiFe2O4 catalyst, which offered advantages lower particle size and better crystalline structure without affecting phase planes. Furthermore, efficacy synthesized catalysts evaluated using catalytic degradation Chrysoidine R dye. study designed to evaluate effect different parameters, such as pH, ...
