Efforts have been placed on the study of intro\u00adduc\u00ading first-row tran\u00adsi\u00adtion met\u00adals in Pt-M alloys to reduce the Pt load\u00ading and mod\u00adu\u00adlate geo\u00admet\u00adric, struc\u00adtur\u00adal and elec\u00adtron\u00adic effects.

The trans\u00adfor\u00adma\u00adtion from face-cen\u00adtered cubic (fcc) to ordered face-cen\u00adtered tetrag\u00ado\u00adnal (fct) struc\u00adture was achieved via ther\u00admal anneal\u00ading. Depend\u00ading on the selec\u00adtion of trans\u00adfor\u00adma\u00adtion meth\u00adods, dif\u00adfer\u00adent degrees of order\u00ading were intro\u00adduced and fur\u00adther cor\u00adre\u00adlat\u00aded with their ORR per\u00adfor\u00admance.
