In this work, uniform cobalt and nickel bimetallic oxides were formed by calcining the carbon templates, which were then modified on a glassy carbon electrode (cobalt–nickel oxide/GCE) as a novel system for the preparation of an electrochemical sensing platform. The electrochemical oxidation behavior of Rhodamine B (RB) at the cobalt–nickel oxide/GCE was investigated using differential pulse voltammetry under optimal conditions; the high electrocatalytic activity of the modified electrode toward analysis of RB was indicated. In addition, a linear range of 0.03−1.0 μmol L–1 and a low detection limit of 5.3 nmol L–1 (S/N = 3) for RB detection were obtained. Finally, the developed method with good stability and sensitivity was successfully applied for RB determination in food samples extract.
