Prospects of carbon capture, utilization and storage for mitigating climate change

“…However, microporous carbon had a higher adsorption capacity, i.e. ; it seems adsorption depends on the narrow space (<1 nm) rather than the surface area or pore space of activated carbon (74).…”

Adsorption of heavy metal onto biomass-derived activated carbon: review

“…Three important factors including specific surface area, pore structure, and surface chemical functional group would affect the adsorption capacity of biomass-derived activated carbon. 208,209…”

“…Three important factors including specic surface area, pore structure, and surface chemical functional group would affect the adsorption capacity of biomass-derived activated carbon. 208,209 4.1.1 Specic surface area. For any adsorbents, a large specic surface area usually means superior adsorption performance, because the surface area provides adsorption space in the adsorption process.…”
