Ultra-high surface area ionic-liquid-derived carbons that meet both gravimetric and volumetric methane storage targets

Abstract

Activation of N-rich and O-poor carbonised matter from ionic liquids yields ultraporous carbon (4000 m2 g−1 and 3.3 cm3 g−1) with high packing density that translates to methane uptake of up to 0.53 g g−1 and 289 cm3 (STP) cm−3 at 25 °C and 100 bar.
