Fabrication of Pt-Re atomic alloy catalysts by alloying of atomically dispersed Pt with Re inside the β-zeolite pores for an oxygen reduction reaction

Abstract

The Pt-Re atomic alloy is fabricated by alloying of atomically dispersed Pt with Re inside the β-zeolite pores with a size of 0.5-0.6 nanometres. The atomically dispersed Pt-Re alloy species exhibit a surprisingly high mass activity of about 60 A g-1Pt for the oxygen reduction reaction, which is much higher than that of the existing Pt nanoparticle catalysts with a Pt particle size of several nanometres.
