Fig. 8. Comparison of the catalytic efficiency of CoFe2O4/ZnO and its bare nanocatalysts under ambient conditions within 15 minutes of catalytic degradation (a) and catalytic degradation of AB113 in the presence of the magnetically recyclable CoFe2O4/ZnO nanocatalyst for six cycles (b). The concentrations were as follows: [AB113] = 5 × 10−5 M and [CoFe2O4/ZnO] = 2.5 g L−1.
