^aS_BET is the Brunauer-Emmett-Teller (BET) specific surface area. ^bS_micro is the t-plot-specific micropore surface area calculated from the N₂ adsorption-desorption isotherm. ^bS_meso is the specific mesopore surface area estimated by subtracting S_micro from S_BET. ^cPore size distribution is obtained by DFT method. ^dV_t is the total specific pore volume determined by the adsorption branch of the N₂ isothermat P/P₀ = 0.99. ^eV_micro is the t-plot-specific micropore volume calculated from the N₂ adsorption-desorption isotherm. ^fV_meso is the specific micropore volume calculated by subtracting V_micro from V_t. ^gCalculated by the Scherrer equation in the XRD profiles. ^hMetal content was determined through ICP-OES analysis.
