  • Electrocatalyst and enzymatic electrode
    Patent number: 8361662
    Abstract: A novel electrocatalyst made of an oxidase having high electron transfer efficiency and an enzymatic electrode using the same are provided. The electrocatalyst is made of CueO. The enzymatic electrode comprises a carbonaceous porous body and an electrocatalyst made of CueO supported on the surface of the carbonaceous porous body. CueO is preferably CueO from Escherichia coli. The carbonaceous porous body constituting the enzymatic electrode is preferably carbonaceous gel. Also, the enzymatic electrode may further comprise a mediator which facilitates transfer of electron between the carbonaceous porous body and said CueO.
