Fig. 4

a Normalized 1H MAS NMR of Ag/nano-Al2O3 with different silver loadings (0, 1, 2, 4, 8%) (Samples were dehydrated at 473 K for 12 h before NMR measurements), b peak resolving of OH consumption peaks after in situ DRIFTS of NH3 adsorption over Ag/nano-Al2O3 with different silver loadings (0, 1, 2, 4, 8%), c relationship between Ag content and peak areas of hydroxyl groups, d peak resolving of OH consumption peaks after in situ DRIFTS of NH3 adsorption over nano-Al2O3 and micro-Al2O3.
