▎ 摘  要

NOVELTY - Preparation of oxidation graphene-polypyrrole/silver bi-functional material integrated with catalytic degradation and detection, involves: (1) dispersing lithium perchlorate, pyrrole and graphene oxide (GO) in phosphate buffer solution of pH 2, to form mixed solution; (2) taking copper sheet as anode, platinum net as cathode, and prepared mixed solution as electrolyte, electrolyzing under nitrogen atmosphere, then washing, drying to form copper/graphene oxide/ polypyrrole (Cu-GO-PPY) composite material; (3) soaking the Cu-GO-PPY composite material in silver nitrate solution, then dripping ascorbic acid solution, reacting for preset time, washing and drying. USE - Method is used for preparing oxidation graphene-polypyrrole/silver bi-functional material used for catalytic degradation or detection of dye (claimed). ADVANTAGE - The method enables to prepare bifunctional material having broad spectrum, which brings about the complete degradation of different dyes, while detecting the degraded dye component, and has preset selectivity.
