A Nicholson and Shain’s plot of oxidation peak potential vs. the Naperian logarithm of different potential scan rates of 5, 15, 25, 50, 80, 100, 150, 250, 300, 400, 600, 800 and 900 mV s− 1 in PBS (0.1 M) pH 6 containing 500 µM RC. B Tafel’s plot of oxidation peak potential vs. the logarithm of the peak current for the electro-oxidation of 500 µM RC on the surface of ZnFe2O4/NPs/IL/CPE at the scan rate of 25 mV s− 1 in PBS (0.1 M) pH 6 containing 500 µM RC.
