Au mass-specific activities (molCO molAu–1 min–1) calculated from experiments at 10 min in CO oxidation reaction under humid conditions: (a) 1.3 Au/f-beta, 0.48 Au/f-beta, 0.28 Au/f-beta, and 1.1 Au/u-beta and (b) 0.48 Au/f-MFI, 0.28 Au/f-MFI, 0.12 Au/f-MFI, and 0.48 Au/u-MFI. Reaction conditions: weight hour space velocity (WHSV) = 0.0619 h–1, temperature = 40 °C, CO/H2O/O2/Ar = 0.5:5:10:84.5.
