A series of [PdCl(2)L(2)] complexes (L=substituted pyridine and pyrazole) has been tried as an electrocatalyst for the reduction of CO2 in acetonitrile (AN) containing 0.1M tetraethylammonium perchlorate (TEAP) at glassy carbon or Pt electrodes. The complexes working as the catalyst were [PdCl(2)L(2)] (L=Pyrazole (Pyra), 4-Methylpyridine (4-Mpy) and 3-methylpyrazole (3-Mpyra)) at an applied potential of -1.10V vs Ag/10mM Ag+ and the reduction products were formic acid and H-2 with no CO. The current efficiency for the formation of formic acid were 10, 20 and 10.2% for Pd complexes of Pyra, 4-Mpy and 3-Mpyra, respectively. The current efficiency for the hydrogen evolution were 31-54%, and the source of the formate proton and hydrogen was from the added water (4% by volume).
