The electro-oxidation of the mixture of formaldehyde and 2-propanol on gold (100) and (111) single crystal planes in alkaline medium
The effect of formaldehyde on the oxidation of 2-propanol and vice versa on gold single crystal planes (100 and 111) was studied. An activating effect in the reaction of the simultaneous oxidation of 2-propanol and formaldehyde was obtained on a gold (100) plane. In the case of a gold (111)...

| Summary: | The effect of formaldehyde on the oxidation of 2-propanol and vice versa on
gold single crystal planes (100 and 111) was studied. An activating effect
in the reaction of the simultaneous oxidation of 2-propanol and formaldehyde
was obtained on a gold (100) plane. In the case of a gold (111) electrode,
the activation effect was not obtained. It was concluded that the adsorption
of formaldehyde on the electrode surface prevents the adsorption of
poisoning species formed during the electro-oxidation of 2-propanol on the
Au(100) plane, while this is not the case on the Au(111) plane. The
different behaviour is caused by the difference in the symmetry of the
surface atoms of these two Au single-crystal planes. |
