NOVELTY - Preparation of enzyme catalyzed three-dimensional porous graphene-carbon nanotube electrode involves mixing graphene oxide solution and a carbon nanotube, stirring for 1-2 hours, placing the mixed solution in a reactor and reacting for 160-180 degrees C for 10-12 hours to obtain a hydrogel and freeze-drying to obtain powdery three-dimensional porous composite material, immersing the composite material in N,N-dimethylformamide and ultrasonically processing for 30-60 minutes to obtain a uniform dispersion, coating the dispersion on a glassy carbon electrode. USE - Preparation of enzyme catalyzed three-dimensional porous graphene-carbon nanotube electrode. ADVANTAGE - The prepared electrode has good electroconductivity and enhances electron transport rate. The electrode structure provides more attachment sites for glucose oxidized enzymes.
