The reactions of formic acid and formaldehyde were studied individually on the clean and oxygen-predosed Pd(100) surface by using temperature-programmed reaction and vibrational spectroscopies. On the clean surface formic acid partially decomposes to give CO, while formaldehyde dehydrogenates to CO and H/sub 2/. The formate species was identified on the oxygen-precovered surface in each case. This result clearly shows that the pattern of activation by oxygen via nucleophilic attack of electron-deficient centers or Bronsted basicity previously reported on copper, silver, and gold single-crystal surfaces is also exhibited on the group VIII metal palladium.
