Precise tuning of pore size distribution in amorphous carbon molecular sieves at the sub-angstrom scale via a synergic mechanism of pore-making and shrinking for separating similar gases

Precise tuning of the PSD in amorphous carbon via a synergistic mechanism of pore-making and shrinking enables successful preparation of a rice-derived CMS, with exceptional performance of sieving propylene from propane with 0.44 Å resolution.
