Interface tension-induced synthesis of monodispersed mesoporous carbon hemispheres.

Here we report a novel interface tension-induced shrinkage approach to realize the synthesis of monodispersed asymmetrical mesoporous carbon nanohemispheres. We demonstrate that the products exhibit very uniform hemispherical morphology (130 × 60 nm) and are full of ordered mesopores, endowing them high surface areas and uniform pore sizes. These monodispersed mesoporous carbon hemispheres display excellent dispersibility in water for a long period without any aggregation. Moreover, a brand new feature of the mesoporous carbon materials has been observed for the first time: these monodispersed mesoporous carbon hemispheres show excellent thermal generation property under a NIR irradiation.
