H2 storage in microporous carbons from PEEK precursors
Large surface area (524-3275 m2/g) microporous carbons (MPCs) derived from poly (etheretherketone), or PEEK, have been synthesized and categorized for their roles as H2 storage materials. It was found that, because of their very large surface areas (≥3000 m2/g), larg cumulative pore volumes (∼ 1.7 cm3/g), and small pore sizes (predominantly ≤ nm), these materials displayed impressive H2 sorption properties, including excess gravimetric and volumetric H2 storage capacities of approximately 5 wt % and 35 g/L, respectively, at 77 K and 20 bar. © 2010 American Chemical Society.
