文摘

A pin-hole below ten micron covered with a Teflon film as gas inlet for in-situ mass spectra. The PtIr alloys exhibit faster kinetic for CO-stripping than Pt and Ir independently. The PtIr alloys exhibit higher CO2 current efficiency (up to 20%) than that on Pt (below 10%). Ir causes higher current efficiency in ethanol oxidation process based on the Pt/C.
