Combined experimental and simulation study on H storage in oxygen and nitrogen co-doped activated carbon derived from biomass waste: superior pore size and surface chemistry development.

In this study, heteroatom (O, N)-doped activated carbon (AC) is produced using urea and KOH activation from abundant and cost-effective biomass waste for H storage. The O and N co-doped AC exhibits the highest specific surface area and H storage capacity (2.62 wt%), increasing by 47% from unmodified AC at -196 °C and 1 bar.
