▎ 摘　　要

The paper describes two preparation methods for the non-covalent functionalization of N-doped graphene with iron(III)-tetrapyridylporphyrin. The obtained nanomaterials show enhanced peroxidase-like activity compared to N-doped graphene and effectively oxidize 3,3'-dimethylbenzidine with hydrogen peroxide with the formation of a blue product. The catalytic activity and implicitly the color intensity are dependent on the hydrogen peroxide concentration, thus creating the possibility for its quantification by UV-Vis spectroscopy. In addition, the nanomaterial obtained by direct functionalization was investigated for its catalytic ability to remove bisphenol A from pH neutral water solutions.
