A porous diamond carbon framework: a new carbon allotrope with extremely high gas adsorption and mechanical properties

Abstract

Since the C60 and graphene were discovered, carbon allotropes have attracted an increasing attention. Here we designed a porous diamond-like carbon framework (named as D-carbon) by inserting –C[triple bond, length as m-dash]C– linkers into all the C–C bonds in a diamond, which is a new carbon allotrope formed by sp3–sp hybridized carbon atoms. Interestingly, the porous D-carbon exhibits a high bulk modulus of 91.7 GPa, which is one order of magnitude larger than other porous MOF and COF materials. Moreover, the D-carbon also shows an extremely high excess volumetric methane uptake of 255 v(STP)/v at 298 K and 35 bar, largely exceeding the target (180 v(STP)/v) of US DOE and all other porous materials.
