CN denotes “coordination number”; R denotes “bond distance”; σ denotes “Debye-Waller factor”; Fresh 5 wt% Pd-doped carbon aroegel samples denote the as-synthesized materials that were oxidized and converted into PdO species instantly in the synthetic processes; 5 wt% Pd-doped carbon aroegel samples were reduced at 453 K under flowing hydrogen gas for six hours. |
