摘要：
Magnetic yolk-shell structured anatase-based microspheres were fabricated through successive and facile sol-gel coating on magnetite particles, followed by annealing treatments. Upon loading with gold nanoparticles, the obtained functional magnetic microspheres as heterogeneous catalysts showed superior performance in catalyzing the epoxidation of styrene with extraordinary high conversion (89.5%) and selectivity (90.8%) towards styrene oxide. It is believed that the construction process of these fascinating materials features many implications for creating other functional nanocomposites. [graphic not available: see fulltext]
