NOVELTY - The utility model claims a graphene-three-dimensional carbon nanotube-palladium nano-particle complex enzymatic hydrogen peroxide electrochemical sensor includes glassy carbon electrode, the glassy carbon electrode top surface is paved with the graphene, the glassy carbon electrode and upper layer of graphene is also paved with three-dimensional carbon nano tube, the said three dimension carbon nanometre tube and graphene are provided with palladium nanoparticles. In the technical solution provided by the graphene-three-dimensional carbon nanotube-palladium nano-particle complex enzymatic hydrogen peroxide electrochemical sensor, the palladium nano-particles on the surface of glassy carbon electrode with good dispersion and large effective active area through three-dimensional carbon nano-tube network the conductive accelerates electrons through the graphene material transfer between the glassy carbon electrode and palladium nano particle catalyst, the performance of this utility model is greatly improved, and has a broad linear range, good sensitivity and high response speed. the stability and anti-jamming ability of itself is also improved.
