A bottom-up approach was employed for the large-scale production of 2D graphene-based nanosheets which have a sandwich structure and consist of silica, carbon, and metal or metal oxide (see picture). These nanosheets exhibit many unique features such as a large aspect ratio, high surface area, and high monodispersibility, which render them suitable for broad application in catalysis, sensors, and batteries.
