Abstract
Improved performance and reduced costs are crucial to develop catalysts for direct formic acid fuel cells. In this study, PdBi alloy nanoparticles were synthesized using a facile seed-mediated growth method. The as-synthesized Pd1Bi1 alloy nanoparticles exhibited a large electrochemical surface area (46.3 m2 g−1) and a high mass activity (1.44 A mg−1), which was 1.19- and 4.8-fold higher than that of commercial Pd/C catalysts, respectively. The PdBi alloy nanoparticle is a promising catalyst for direct formic acid fuel cells.
