(a) Aerobic oxidation of methanol to methyl formate (MeFm) as a function of the total Ag content in the samples determined by atomic absorption spectroscopy (AAS) obtained by free corrosion, potentiostatic dealloying, and galvanostatic dealloying. (b) Partial aerobic oxidation of ethanol as a function of Ag content in NPG obtained by GD. The corresponding aldehyde and ester are formed in a ratio of 1:1 at low Ag contents of 1 at. %, yet aldehyde formation increases with increasing Ag content. Experiments were performed at 3 bar O2 pressure at 60 °C for 24 h. Reproduced with permission from ref (185). Copyright 2017 Royal Society of Chemistry.
