In article number 1606215, Tierui Zhang and co‐workers present a silica‐protected calcination strategy to synthesize “naked” magnetically recyclable mesoporous Au‐γ‐Fe 2 O 3 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‐Fe 2 O 3 and considerable Au/γ‐Fe 2 O 3 interfaces.
