▎ 摘　　要

NOVELTY - Preparing three-dimensional graphene composites based on benzyl alcohol route comprises hydrothermally synthesizing nano particle with a benzyl alcohol as a solvent, preparing a three-dimensional zinc ferrite/graphene oxide/glassy carbon electrode (GCE) composite material by graphene and three-dimensional zinc ferrite/graphene oxide/GCE composite modified glassy carbon electrode. USE - The method is useful for preparing three-dimensional graphene composites based on benzyl alcohol route. ADVANTAGE - The method is easy to prepare and preserve and has good stability, good selectivity to p-nitrophenol and high sensitivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the application of the benzyl alcohol-based route for preparing the three-dimensional graphene composite comprising passing a sulfuric acid solution containing p-nitrophenol through a nitrogen gas and modifying by a three-dimensional zinc ferrite/graphene oxide/GCE composite material, where the glassy carbon electrode is the working electrode, the saturated calomel electrode is the reference electrode and the platinum electrode is the counter electrode.
