Rational synthesis of hierarchical magnetic mesoporous silica microspheres with tunable mesochannels for enhanced...

Hierarchical magnetic mesoporous silica microspheres (MMSMs) with a core-shell structure have been fabricated through an improved water/oil biphase synthesis strategy. We firstly reported that the mesopore size can be readily tuned from 6.1 to 11.4 nm by the synergistic effect of surfactant concentration and an amphiphilic agent, thus holding a bright future in many possible applications.
