Catalysts: “Naked” Magnetically Recyclable Mesoporous Au–γ‐Fe2O3 Nanocrystal Clusters: A Highly Integrated Catalyst System (Adv. Funct. Mater. 9/2017)

In article number 1606215, Tierui Zhang and co-workers present a silica-protected calcination strategy to synthesize “naked” magnetically recyclable mesoporous Au-γ-Fe2O3 clusters. The clusters show outstanding catalytic performance in the reduction of 4-nitrophenol and enhanced performance in the catalytic oxidation of CO, due to their “naked” surfaces, small Au nanoparticle size, inherent magnetism of γ-Fe2O3 and considerable Au/γ-Fe2O3 interfaces.
