Super-paramagnetic nano-Fe₃O₄/graphene for visible-light-driven hydrogen evolution

Abstract

A super-paramagnetic nano-architecture, which could be separated and re-dispersed easily for reuse, was designed for effective dye-sensitized H2 evolution. By the enhancement of electron-transfer and surface-repair ability of graphene, the visible-light-driven hydrogen evolution rate over the exposed Pt(111) facet loaded Fe3O4/GO catalyst was remarkably enhanced.
