• Abstract:The development of safe and efficient hydrogen storage/release systems is critical for achievement of a fuel-cell-based hydrogen economy. In this work, ultrafine PdAg NPs with the size of 2.5 nm were successfully immobilized on cerium oxide/nitrogen-doped carbon (CeOx-NPC). By virtue of strong metal/support interactions, the obtained PdAg/CeOx-NPC exhibits excellent catalytic activity in FA decomposition at room temperature and the turnover frequency (TOF) reaches a high value of 875 h(-1). The remarkable catalytic property of PdAg/CeOx-NPC results from the small and highly dispersed PdAg NPs and the synergistic effect of the bimetallic system. Also, the strong metal-support interaction efficiently improves the catalytic properties of the bimetallic catalytic system.
