Comparison of catalytic efficiency (of the 1%Ag/CeMnO_x catalysts with similar catalysts available literature data.

Catalyst	Reaction Conditions					NO Reduction Efficiency			Ref.
	NO, ppm	O2, vol.%	C3H6, vol.%	H2, vol.%	WHSV, mL g−1 h−1	X(NO), %	S(N2), %	Y(N2), %
1%Ag/CeMnOx	1000	10	3600	2.9	25,000	44	91	40	This work
1%Ag/CeMnOx	1000	10	3600	-	25,000	46	86	40	This work
1%Ag/CeMnOx (aged)	1000	10	3600	-	25,000	44	90	40	This work
1%Ag/CeZrOx	700	3	700	0.5	45,000	80	60	48	[28]
1%Ag/CeZrOx	700	3	700	-	45,000	50	30	15	[28]

WHSV is the weight hourly space velocity; X(NO) is NO conversion, S(N₂) is N₂ selectivity and Y(N₂) is yield.
