文摘

We report a facile 鈥渉ydrothermal etching assisted crystallization鈥?route to synthesize Fe₃O₄@titanate yolk-shell microspheres with ultrathin nanosheets-assembled double-shell structure. The as-prepared microspheres possess a uniform size, tailored shell structure, good structural stability, versatile ion-exchange capability, high surface area, large magnetization, and exhibit a remarkable catalytic performance.
