Magnetically recyclable CoFeO/ZnO nanocatalysts for the efficient catalytic degradation of Acid Blue 113 under ambient conditions.

CoFeO/ZnO magnetic nanocatalysts were synthesized using a low-frequency ultrasound-assisted technique to enhance the optical, morphological, magnetic and catalytic properties of ZnO. The as-synthesized nanocatalysts were characterized by XRD, Raman, TEM, DR-UV-Vis and VSM analyses in order to confirm the expected modifications of the resulting nanocatalysts. The Raman spectral analysis revealed substitutional Zn in the CoFeO/ZnO nanocatalyst.
