  1. a From inductively coupled plasma optical emission spectroscopy (ICP-OES)
  2. b From argon physisorption using Brunauer–Emmett–Teller (BET) method
  3. c Calculated from the diffraction peak at 2θ = 22.4°, the corresponding calcined materials were taken as 100%
  4. d Integrated value from ammonia desorption peak at 250–550 °C (Supplementary Fig. 5)
