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.
