Three-dimensional network model of carbon containing only sp2-carbon bonds and boron nitride analogues.

We design two network models of carbon and boron nitride crystalline networks, namely, the honeycomb and triangular foams. The triangular carbon foam is a unique 3D network model of carbon which contains only sp(2)-carbon bonds. Also, it has large internal surface area per unit volume and bulk modulus. © The Royal Society of Chemistry 2011
