High performance photocatalytic metal oxide synthetic bi-component nanosheets formed by atomic layer deposition

Abstract

Synthetic nanosheets that are ultrathin variants of bulk materials have been acquired using atomic layer deposition (ALD) on dissolvable substrates with a control over layer dimension including single and bilayered “Janus nanosheet” structures. TiO₂, ZnO, Al₂O₃ and TiO₂/ZnO nanosheets function as dispersible photocatalysts in aqueous media showing 3× synergistic rate enhancement for bilayered nanosheets.
