Synthesizing Pd-based high entropy alloy nanoclusters for enhanced oxygen reduction

We report the synthesis of uniform Pd-based high-entropy alloy clusters via rapid Joule heating. The quinary PdMnFeCuNi clusters exhibit 4.95 times higher mass activity than the Commercial Pt/C for the oxygen reduction reaction, and outstanding stability with only 2 mV decay in the half-wave potential after 20 000 cycles of testing. We report the synthesis of uniform Pd-based HEA clusters on an XC-72 carbon support using a rapid Joule heating method. The quinary PdMnFeCuNi clusters exhibit outstanding stability and 4.95 times higher mass activity than the Com Pt/C for the ORR.
