摘要	Poly(vinylidene chloride)-based carbon (PC) with ultrahigh microporisity was prepared by simple carbonization and KOH activation, exhibiting great potential to be superior CO2, CH4, and H-2 adsorbent at high pressures. The CO2 uptake for pristine PC is highly up to 3.97 mmol/g at 25 degrees C and 1 bar while the activated PC exhibits a slightly lower uptake at 1 bar. However, the activated PC has an outstanding CO2 uptake of up to 18.27 mmol/g at 25 degrees C and 20 bar. Gas uptakes at high pressures are proportional to the surface areas of carbons. The CH4 uptake for the activated PC is up to 10.25 mmol/g (16.4 wt % or 147 v/v) at 25 degrees C and 20 bar which is in a top-ranked uptake for large surface area carbons. Furthermore, H2 uptake on the activated PC reaches 4.85 wt % at -196 degrees C and 20 bar. Significantly, an exceptionally large H-2 storage capacity of up to 2.43 wt % at 1 bar was obtained, which is among the largest value reported to date for any porous adsorbents, to the best of our knowledge. The ease of preparation and large capture capacities endow this kind of carbon attractive as promising adsorbent for CH4, H-2, and CO2 storage.
