A Highly Sensitive Non-Enzymatic Glucose Electrochemical Sensor Electrode Material of CuO Nanospheres/Activated Carbon Composites
The electrode materials of copper oxide (CuO) nanospheres composite activated carbon (AC) (CuO/AC) were prepared by a hydrothermal method. CuO/AC and chitosan (CTS) were immobilized on the surface of the glassy carbon electrode (GCE) to construct a non-enzymatic glucose electrochemical sensor (CuO/A...

| description | The electrode materials of copper oxide (CuO) nanospheres composite activated carbon (AC) (CuO/AC) were prepared by a hydrothermal method. CuO/AC and chitosan (CTS) were immobilized on the surface of the glassy carbon electrode (GCE) to construct a non-enzymatic glucose electrochemical sensor (CuO/AC + CTS + GCE). The results show that an average particle size of spherical CuO is about 500 nm, which evenly distribute on the surface of AC. The nanocomposites have a large surface area, more active sites, and higher electron transfer ability. CuO/AC + CTS + GCE-2 with a Cu
