- •
3D porous hybird aerogel assembly of Bi2WO6 nanosheets and graphene was firstly prepared via a facile solvothermal route.
- •
The Rhodamine B (RhB) removal ratio over the 3D hybird aerogel photocatalyst reaches up to 99.6% within 45 min
- •
Graphene could promote the separation of photocarriers by removing photo-generated electrons from Bi2WO6.
- •
The O2−• is the main active species for the degradation of the RhB.
