															Abstract:  Graphene aerogel not only has the inherent flexibility, excellent electrical and mechanical properties of graphene, but also has the characteristics of high specific surface area, low density, and large porosity. Its unique three-dimensional structure is very conducive to the introduction of other functional materials, thus giving the composite materials more excellent performance. Protoporphyrin possesses a highly conjugated structure and can make full use of the catalytic function after combining with the metal ions. Based on this, the π-π interaction between graphene and protoporphyrin was used in this work. The protoporphyrin with a certain concentration was assembled on the graphene aerogel, which contributed to the fabrication of the graphene/porphyrin composite aerogel materials. The process is simple and easy to operate. The micro-morphology and composition of the composites were analyzed in this work. The effect of the assembly of protoporphyrin on the conductivity of graphene aerogel and the detection function for NO3 -  of the graphene/porphyrin composite aerogel materials were studied. The results show that the prepared composites have a uniform three-dimensional porous structure, and the resistance of the graphene aerogel is reduced obviously after the introduction of protoporphyrin molecules. The three-dimensional aerogel structure can effectively realize the composite of protoporphyrin with graphene and achieve the sensitive detection of NO3 - .
