Facile synthesis strategy of NicorePtshell electrocatalyst for oxygen reduction reaction

摘要

Polymer electrolyte membrane fuel cells(PEMFCs), as an energy conversion technology, have attracted extensive attention due to their high conversion efficiency, low emission, high energy density,and fast fuel charging [1,2]. Pt-based catalysts have been acknowledged to be the most effective catalyst for the oxygen reduction reaction(ORR) [3–5]. However, both the source scarcity and high cost of Pt severely hinder the commercial application of the PEMFCs [1,6,7].
