Table 1 Properties of biomass-derived biochar by chemical activation

Activator Physical and chemical properties Ref. H3PO4 larger surface area and larger portion of mesoporous [26] HNO3 increased the cation exchange capacity and number of carboxylic acid groups [27] H2SO4 increase the porosity in carbon structure and number of -SO3H groups [28] KOH higher microporosity and the larger specific surface area [29] ZnCl2 larger specific surface area and mesoporous structure [30]
