title: Bilayered Biofoam for Highly Efficient Solar Steam Generation.
abstract: A novel bilayered hybrid biofoam composed of a bacterial nanocellulose (BNC) layer and a reduced graphene oxide (RGO)-filled BNC layer is introduced for highly efficient solar steam generation. The biofoam exhibits a solar thermal efficiency of ≈83% under simulated solar illumination (10 kW m-2). The fabrication method introduced here is highly scalable and cost-efficient.
