Porous carbons have been extensively investigated for hydrogen storage but, to date, appear an upper limit their capacity. Here, in effort circumvent this limit, we explore the potential of oxygen-rich activated carbons. We describe cellulose acetate-derived that combine high surface area (3800 m2 g-1) and pore volume (1.8 cm3 arise almost entirely (>90%) from micropores, with nature. The exhibit enhanced gravimetric uptake (8.1 wt% total 7.0 excess) at -196 °C 20 bar, rising a 8.9 30...
Cigarette butt derived carbons are highly porous (4310 m<sup>2</sup> g<sup>−1</sup> and 2.09 cm<sup>3</sup> g<sup>−1</sup>) with record levels of hydrogen storage.
Activation of N-rich and O-poor carbonised matter from ionic liquids yields ultraporous carbon (4000 m 2 g −1 3.3 cm 3 ) with high packing density that translates to methane uptake up 0.53 289 (STP) −3 at 25 °C 100 bar.
Subtle changes in PSDs of carbons are better observed using dual isotherm O 2 /H porosimetry.
The efforts to increase the active surface area of catalysts led reduction metal particle size, down single atoms.

Activated carbon cloth can be synthesised through a simple carbonisation and activation process, its porosity tuned to either dioxide capture or methane storage.

The relationship between porosity within a given pore size range, and uptake of CO 2 as function pressure.
Activated carbon cloth (ACC) has the potential to be extremely useful in gas capture and storage applications as it combines high porosity, robustness, flexibility with ease of handling. While been produced by a few researchers, synthesis methods used date either do not yield product or if appropriate textural properties are achieved is com- plex arduous. Following systematic study, we show that an almost exclusively microporous flexible ACC can surface area >1900 m2 g−1 via stabilisation...
Porosity, and in particular pore size is the one of most important considerations development porous carbons for CO2 capture. Current methods determining optimum adsorption either make very broad assumptions (in computational studies), or are not sufficiently thorough experimental studies). Herein we present a brute force, first principles method range sizes, Ω, best suited to given sorptive at pressures. This then used determine Ω pressure according N2 porosimetry. The analysis extended...
In this study biochars and activated carbons were synthesized either directly via the pyrolysis of sodium carboxymethyl cellulose (NC) or hydrothermal carbonization sawdust (SD) in an aqueous solution KOH. The amount porogen was varied by modulating degree substitution on NC KOH mixed with SD. Pore size distributions (PSDs) these determined from dual fit kernels based two-dimensional version nonlocal density functional theory (2D-NLDFT) heterogeneous surface models to N2 H2 O2 isotherms...
