Janus mesoporous silica nanosheets with perpendicular mesochannels: affording highly accessible reaction interfaces for enhanced biphasic catalysis.

A Janus mesosilica nanosheet with perpendicular mesochannels has been explored to use as a highly efficient interfacial catalyst for biphasic reactions. Owing to the excellent interfacial activity and the highly accessible reaction interface, a significantly enhanced catalytic activity is presented in aqueous hydrogenation reactions.
