New pentlandite-like oxide semiconductors IrIn₆XYO₈ (X = Ga, In; Y = Ge, Sn, Ti) as potential candidates for photocatalytic water splitting under visible-light irradiation

Abstract

Chemical bond analysis points out that the orbital interactions of the In–O/In bond are responsible for the final band edge structures. This intrinsic band features facilitate visible light absorption and electron migration.
