a b s t r a c t In this study, an activated carbon with high-surface area was prepared from Paulownia (P. tomentose) wood by chemical activation with ZnCl2. The influences of carbonization temperature and impregnation ratio on the pore structure of the activated carbon were investigated. Activation temperatures and impregnation ratios were selected in the range of 400–700 0C and 0.5–4.0…
