Description

technical field

[0001] The invention belongs to the field of biochemical sensors, and relates to a ceria-modified copper hydroxide (CeO 2 -Cu(OH) 2 ) composite electrode and its application in glucose sensor. Background technique

[0002] Copper and its oxides have good catalytic activity, so they are excellent materials for non-enzymatic glucose sensors. Many reported non-enzymatic glucose sensors based on copper and its oxide nanomaterials have been demonstrated for glucose sensing.

[0003] The sensing performance of electrochemical glucose sensors requires not only efficient redox reactions at the electrode / electrolyte interface but also fast electron transport. However, nano-copper materials are easily oxidized, and copper oxides have poor conductivity, which makes the electrodes not sensitive enough. Contents of the invention

[0004] Primary purpose of the present invention is to provide a kind of nanometer CeO 2 -Cu(OH) 2 composite electrode.
