▎ 摘　　要

NOVELTY - A graphene oxide and acid-treated carbon nanotubes are uniformly dispersed, to prepare a homogeneous dispersion mixed aqueous solution. The homogeneous dispersion mixed aqueous solution is subjected to hydrothermal production. Thus, hydrothermal production of graphene/carbon nanotubes complex aerogel is enabled. USE - Hydrothermal production of graphene/carbon nanotubes complex aerogel used for forming film used as porous material electrode component of uric acid, dopamine, ascorbic acid separation sensing electrode (all claimed). ADVANTAGE - The method enables quick and safe hydrothermal production of graphene/carbon nanotubes complex aerogel by an easy method without using a hazardous reducing agent. The electrode material containing graphene/carbon nanotubes complex aerogel has excellent electrochemical characteristics. The catalyst material containing graphene/carbon nanotubes complex aerogel has high activity. The separation of uric acid, dopamine and ascorbic acid can be selectively detected using the graphene/carbon nanotubes complex aerogel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for uric acid, dopamine, ascorbic acid separation sensing electrode, which comprises an electrode and a film containing the hydro-thermally produced graphene/carbon nanotubes complex aerogel as a porous material electrode component which covers the electrode plane of the electrode.
