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

摘要

The Pta??Re atomic alloy is fabricated by alloying of atomically dispersed Pt with Re inside the $eta$-zeolite pores with a size of 0.5a??0.6 nanometres. The atomically dispersed Pta??Re alloy species exhibit a surprisingly high mass activity of about 60 A g$^{a??1}_{m Pt}$ 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.
