▎ 摘 要
A BiOBr/reduced graphene oxide (RGO) composite aerogel with BiOBr nanoplates grown on an interconnected three-dimensional RGO-based porous network was prepared by one-pot hydrothermal method using L-lysine as a reducing agent and the cross-linker. Its enhanced adsorption toward pollutants owing to its large Brunauer-Emmett-Teller specific surface area and spongy nature, improved light absorption due to its extremely lightweight nature and the RGO promoting photogenerated charge separation contributed to the BiOBr/RGO aerogel's enhanced activity for photocatalytic degradation in an aqueous system. The BiOBr/RGO aerogel also showed high stability and can be easily separated from the reaction systems for recycling. The facile one-pot method has been proved to be generic in the formations of different semiconductor embedded RGO aerogels like BiOX/RGO (X = Cl and I), CdS/RGO and Fe2O3/RGO aerogels, which combine the advantages of enhanced photocatalytic activity with facile recycling for applications in aqueous photocatalytic reaction systems.
