Formic acid dehydrogenation on au-based catalysts at near-ambient temperatures.
Selective HCOOH decomposition to H(2)/CO(2) on Au: Au species catalyze HCOOH dehydrogenation at higher rates than on Pt, previously considered the most active metal. Dehydrogenation occurs through formate decomposition limited by H(2) desorption on Au species undetectable by TEM. CO did not form (<10 ppm), making products suitable for low-temperature fuel cells.
