Enzyme-free glucose sensor using a glassy carbon electrode modified with reduced graphene oxide decorated with mixed copper and cobalt oxides

We describe a binary porous catalyst consisting of a reduced graphene oxide (rGO) support decorated with mixed Cu-Co oxides. It was synthesized electrochemically and characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy and cyclic voltammetry. The nanocomposite was depo... Full description

description: We describe a binary porous catalyst consisting of a reduced graphene oxide (rGO) support decorated with mixed Cu-Co oxides. It was synthesized electrochemically and characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy and cyclic voltammetry. The nanocomposite was deposited on a glassy carbon electrode (GCE) where it exhibits better electrocatalytic activities for glucose oxidation compared to GCEs modified with CuO x or CoO x only on an rGO support. The improved electrocatalytic activities are believed to result from the synergistic effect of CuO x -CoO x binary catalyst, the high conductivity of rGO support, and the porous scaffold. The amperometric sensor, operated in 0.1 M NaOH at a working potential of +0.5 V (vs. SCE), displays a calibration plot for glucose that is linear in the 5 to 570 μM concentration range, and the detection limit is 0.5 μM. The performance of the sensor was evaluated by determination of glucose in (spiked) human urine. Graphical abstract A binary porous catalyst consisting of a reduced graphene oxide (rGO) support decorated with mixed Cu-Co oxides was synthesized on glassy carbon electrode (GCE) through a two-step electrochemical method and used as electrocatalyst for direct oxidation of glucose.
