Magnetic graphene noble metal aerogels: preparation and application for catalytic degradation of 4-NP

In this work, the preparation of magnetic graphene noble metal aerogels (GA-Fe3O4-Au-(ethanol)) was realized by self-assembly induced by radiation reduction. The prepared material GA-Fe3O4-Au-(ethanol) can be easily attracted by a magnet. Meanwhile, GA-Fe3O4-Au-(ethanol) successfully realized the degradation of 4-nitrophenol (4-NP), which was considered an environmentally harmful pollutant. It is worth mentioning that the prepared materials showed a better catalytic performance than general noble metal catalysts, and it was found that the content of noble metals in the fabricated composite significantly influenced the catalytic reaction rate. The successful preparation of this material provides a feasible scheme for treating pollutant 4-NP.
