  1. aBET (Brunauer-Emmett-Teller) surface area
  2. bThe micropore surface area S Micro and micropore volume V Micro were calculated from the t plot method
  3. cThe mesopore surface area (S Meso) and mesopore volume (V meso) were calculated from the BJH (Barrett-Joyner-Halenda) method
  4. dTotal pore volume, measured at P/P 0 = 0.99
  5. eAverage pore size, calculated by 4 V Total/S BET
