Abstract: | The safe and efficient storage and release of hydrogen are widely recognized as the main challenges for the establishment of a fuel‐cell‐based hydrogen economy. Formic acid (FA) has great potential as a safe and convenient source of hydrogen for fuel cells. Despite tremendous efforts, the development of heterogeneous catalysts with high activity and relatively low cost remains a major challenge. The synthesis of AuPd–MnOx nanocomposite immobilized on ZIF‐8–reduced‐graphene‐oxide (ZIF‐8–rGO) bi‐support by a wet‐chemical method is reported here. Interestingly, the resultant AuPd–MnOx/ZIF‐8–rGO shows excellent catalytic activity for the generation of hydrogen from FA, and the initial turnover frequency (TOF) reaches a highest value of 382.1 mol H2 mol catalyst?1 h?1 without any additive at 298 K. This good performance of AuPd–MnOx/ZIF‐8–rGO results from the modified electronic structure of Pd in the AuPd–MnOx/ZIF‐8–rGO composite, the small size and high dispersion of the AuPd–MnOx nanocomposite, and also the strong metal‐support interaction between the AuPd–MnOx and ZIF‐8–rGO bi‐support. |
