摘要：

The reaction products of propargyl alcohol (PA), allyl alcohol (AA) and n-propanol (n-PrOH) at different applied potentials have been investigated on Au electrodes in 0.5 M H2SO4. On line mass spectrometry (DEMS) reveals that CO2 and acrolein are formed from bulk AA electro-oxidation. PA electro-oxidation produces CO2 and propargyl aldehyde, and electroreduction yields propyne, propylene and AA. No strongly bound intermediates for AA were detected. PA forms adsorbates which give CO2 and a C3 hydrocarbon during electro-oxidation and electroreduction, respectively. No electrochemical activity could be detected for n-PrOH on Au.
