Intrinsic magnetic characteristics-dependent charge transfer and visible photo-catalytic H2 evolution reaction (HER) properties of a Fe3O4@PPy@Pt catalyst

Abstract

A ternary nano-architectural photocatalyst has been designed to investigate whether the intrinsic magnetic property of photo-catalysts has an effect on the charge transfer and its photo-catalytic H₂ evolution reaction (HER) properties under visible light irradiation. The electron transfer and visible-light-driven hydrogen evolution were remarkably enhanced by regulating the electromagnetic interaction between the magnetic catalysts and the photo-generated electrons.
