Abstract

A black-colored nitrogen-doped calcium niobium oxide nanosheet with a thickness of around 1 nm was prepared by exfoliating nitrogen-doped layered oxide (KCa2Nb3O10−xNy), which exhibited photocatalytic activities superior to those of the parent material under visible light irradiation. It is suspected that the ultrathin thickness is suppressing the recombination.
