In Situ synthesis of SiC-graphene core-shell nanoparticles using …
In this work, we report an in situ synthesis route of SiC-graphene core-shell nanoparticles using wet ball milling. Specifically, graphite flakes were gradually exfoliated into fresh and thin GNSs mechanically in a wet medium. The non-destructive exfoliation of GNSs is ensured by the benefits of wet milling medium at low rotary speed.
