Abstract

Highly dispersed PdCu alloy nanoparticles have been successfully prepared within a macroreticular basic resin bearing -N(CH3)2 functional groups. This previously unappreciated combination of alloy is first proven to be responsible for the efficient production of high-purity H2 from formic acid (HCOOH) dehydrogenation for chemical hydrogen storage. By the addition of Cu, the electronically promoted Pd sites show significantly higher catalytic activity as well as a better tolerance towards CO poisoning as compared to their monometallic Pd counterparts. Experimental and DFT calculation studies revealed not only the synergic alloying effect but also cooperative action by the -N(CH3)2 groups within the resin play crucial roles in achieving exceptional catalytic performances. In addition to the advantages such as, facile preparation method, free of additives, recyclable without leaching of active component, and suppression of unfavorable CO formation less than 3ppm, the present catalytic system is cost-effective because of the superior catalytic activity compared with that of well-established precious PdAg or PdAu catalysts. The present catalytic system is particularly desirable for an ideal hydrogen vector in terms of potential industrial application for fuel cells.
