A simple method for the production of highly ordered porous carbon materials with increased hydrogen uptake capacities

► The first systemically investigation of the effect of heat treatment on templated porous carbons. ► Heat treatment can improve the structure, textural property and H2 uptake of microporous carbons. ► Heat treatment is a simple and general approach to synthesize ordered microporous carbons. ► Optimised microporous carbons exhibited hydrogen storage up to 5.85 wt% at 20 bar and −196 °C ► Heat treatment has no obvious effect on textural properties and H2 uptake for mesoporous carbons.
