A CuO nanothorns/Cu foam (NTs-CuO/Cu foam) was synthesized using a low-cost and facile method. The morphology and composition of the NTs-CuO/Cu foam were characterized using SEM, TEM and XRD. Copper foam as the current collector played a key role in the formation of the NTs-CuO/Cu foam. The CuO nanothorns were freely grown on copper foam, and can make contact with the underneath conductive copper foam directly. The NTs-CuO/Cu foam was used as an electrocatalyst for the detection of glucose in an electrochemical sensor. The CuO nanothorns/Cu foam electrode shows an extremely high sensitivity of 5.9843 mA mM(-1) cm (-2) 2 and a low detection limit of 0.275 mu M based on a signal to noise ratio of 3. Due to its excellently high sensitivity, stability and anti-interference ability, the NTs-CuO/Cu foam will be a promising material for constructing practical non-enzymatic glucose sensors.
