Dysprosium Regulated Platinum Particles as a Bimetallic Alloy Catalyst for Oxygen Reduction Reaction
As an critical half reaction, oxygen reduction reaction is very important in green energy applications. Platinum metal is regarded as an excellent material for electrocatalyst, especially for oxygen reduction reaction. But, the expensive cost and scarce reserves have strongly impeded its further application in energy storage and conversion fields. Recently, Pt-rare earth composites are explored as a promising alternatives. In this work, the Pt-Dy bimetallic alloy was synthesized and its electrocatalytic tests were operated for oxygen reduction reaction. Impressively, excellent mass activity of 594 A·g -1 was generated by Pt-Dy alloy relative to commercial Pt/C catalyst (162.8 A·g -1 ). Furthermore, after an accelerated durability test, the catalytic activity loss for Pt-Dy alloy catalyst reaches 20% while Com Pt/C reduces 56%
