The invention provides a preparation method of a porous graphene-peroxidase modified glassy carbon. According to the method, graphene is etched by adopting silver nanoparticles for the first time to prepare porous graphene, and the porous graphene is taken as a substrate and is loaded with peroxidase to modify a glassy carbon electrode. The method comprises the steps of carrying out a one-pot method to prepare a silver nanoparticle-graphene composite material, and then removing the silver nanoparticles by use of nitric acid to obtain the porous graphene. Peroxidase is fixed to the porous graphene to modify the electrode, and H2O2 is detected by adopting cyclic voltammetry. The method for preparing the porous graphene is simple and easy to operate, and the porous graphene has good chemical inertness and biocompatibility. The porous graphene-peroxidase modified glassy carbon prepared by the method has good electrocatalytic activity for H2O2.
Description
technical field [0001] The invention relates to a method for preparing a porous graphene-horseradish peroxidase modified glassy carbon electrode. Background technique [0002] Graphene (GN) is a new type of two-dimensional carbon-based nanomaterials. Its unique electrical, optical and mechanical properties make it rapidly become a research hotspot in the fields of physics, chemistry and materials science. It has been reported that the properties of graphene can be improved by modifying the structure of graphene (substrate or edge), resulting in new graphene-based materials. In recent years, more and more researchers have begun to pay attention to the potential applications of defects in graphene, and found that many catalytic reactions, electron transfer and chemical reactivity on graphene occur at defect sites. [0003] Porous graphene (PGN) is a modified graphene with many nanoscale holes in its sheets, and this new type of material has better properties than pure graphen...
