Exsolved Ru on BaCe_xO_y Catalysts for Thermochemical Ammonia Synthesis

Table 1

Calculated Ru metal dispersion and specific surface area of impregnated and exsolved catalyst reduced at different conditions.

Catalyst	Metal dispersion (%)	Specific surface area (m^2/g)	Average pore size^a (Å)	Pore volume^b (cm^3/g)
Imp_N2	4.9288	4.0900	119	0.0121
Ex_N2	7.8028	3.1792	132	0.0105
Ex_Ar	0.3909	5.6776	245	0.0347

^aPore size was calculated based on adsorption average pore width (4 V/A by BET). ^bPore volume was calculated by single-point N₂ adsorption.
