Formic Acid Dehydrogenation on Au‐Based Catalysts at Near‐Ambient Temperatures

Formic Acid Dehydrogenation on Au‐Based Catalysts at Near‐Ambient Temperatures

Selective HCOOH decomposition to H2/CO2 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 H2 desorption on Au species undetectable by TEM. CO did not form (
