  1. 1Specific surface area was calculated with the Brunauer–Emmett–Teller (BET) model
  2. 2Total pore volume was calculated from single point adsorption at P/P0 = 0.99
  3. 3Pore volume in each pore size range was obtained from the density functional theory (DFT) analysis
  4. 4Elemental analysis
