The invention discloses a method for preparing a high-sensitivity electrode for formic acid detection. The method uses an electrodeposition method to prepare platinum nanoparticles, uses a graphene-ionic liquid composite film as a substrate for electrodeposition, and combines nano-alloys, ionic liquids, graphene The advantages of the modified electrode, through the steps of cleaning the electrode, preparing graphene-ionic liquid gel, preparing graphene-ionic liquid modified electrode, preparing platinum-graphene-ionic liquid modified electrode, etc., finally obtain platinum m gold n -graphene- Ionic liquid modified electrodes. Using the prepared modified electrode to detect formic acid has the advantages of low preparation cost and high response sensitivity. |
