Formic acid has a great potential as a source of energy for fuel cells from its catalytic decomposition (via hydrogen gas) or electro-oxidation over Pd catalysts.However, unmodified Pd surface are susceptible to poisoning by CO and related molecules which poses severe technical problems for these applications.This work is concerned with enhanced catalytic performances of modified Pd with CO tolerant surface by using nanocubic CeO2 as a catalyst support.
