Abstract

The combination of the pre-formed magnetic (Mn_0.983Fe_0.017)₂O₃ particles with Ta₂O₅ prepared from ionic liquids affords (MnFe)₂O₃@Ta₂O₅ core–shell composites. The photocatalytic activities of these core–shell materials were evaluated for hydrogen production, for which they appeared to be superior catalysts to the individual (Mn_0.983Fe_0.017)₂O₃ and Ta₂O₅ components.
