摘要

Bimetallic CuCo composites are prepared by calcinating copper hexacyanocobaltate precursor in N-2 atmosphere. The CuCo modified electrodes are fabricated for nonenzymatic glucose sensing in the alkaline electrolyte. The glucose can be directly electro-oxidized on the surface of the electrode catalyst mediated by the redox couples of Cu and Co. The optimal glucose sensor exhibits a high sensitivity (567 mu A . mM(-1) . cm(-2)) in the range up to 825 mu M with a detection limit of 3 mu M and acceptable selectivity. The sensor can also be applied in serum samples. This work provides a facile and easily-scalable synthesis method of electrocatalysts for nonenzymatic glucose sensors.
