This study developed a highly active and reusable platinum catalyst for the dehydrogenation of ammonia borane. The catalyst, prepared by alloying and dealloying platinum-aluminum alloy, exhibited the highest hydrogen generation rate and activation energy in methanol solution. Additionally, the catalyst demonstrated high durability when effective washing step was applied after each utilization.
This study aimed to obtain a highly active and reusable catalyst for the dehydrogenation of ammonia borane. A nobel metal platinum catalyst supported on a polymer substrate was produced by the alloying and dealloying of platinum-aluminum alloy. The hydrogen generation rate was dependent on a cosputtering time, the solvent of the ammonia borane solution and temperature. The highest hydrogen generation rate was measured as 122.3 L-1 H-2 min(-1) g(-1) catalyst and the activation energy of the reaction was calculated as 22.7 kJ mol(-1) in methanol solution. Furthermore, the catalyst demonstrated high durability when effective washing step was applied after each utilization.
