Electrodeposited mesoporous (MP) Pt electrodes were evaluated as catalysts for CO and methanol electrooxidation. Electrochemical analysis reveals a mass activity of 41 Ag-1 at 0.55 V in 1 M CH3OH, similar to carbon supported catalysts. However, the high current densities are related to low CO, conversion efficiencies, as was established by using differential electrochemical mass spectrometry in a thin layer flow cell configuration (TLFC-DEMS). These results can be understood taking into account the especially accessible porous structure of the MP Pt, where the possibility of readsorption of partially oxidized products is low.
