Adsorption measurements were conducted using a BELSORP-
Max instrument from BEL Japan Inc. Around 0.1 g of each cata-
lyst was pre-treated under flowing H2 at 200 °C with a heating
ramp of 5 °C min−1 for 30 min, followed by evacuation for 3 h
at the same temperature. Adsorption measurements were per-
formed using hydrogen and propyne at 0 °C. Langmuir iso-
therms, non-dissociative, were fitted to the experimental results
for propyne adsorption leading to the amount of gas adsorbed
per surface metal. In view of the low amount of H2 adsorbed on
both catalysts, it was not possible to fit dissociative Langmuir
isotherms and therefore the results reported here correspond to
the amount of H2 adsorbed at 290 mbar.
