Abstract
Provided is a catalyst for oxygen reduction reaction comprising an alloy comprising at least one selected from Pt, Pd and Ir supported on a carbon carrier functionalized with poly(N-isopropylacrylamide) (PNIPAM). The catalyst for oxygen reduction reaction has electronic ensemble effects by virtue of the carbon carrier functionalized with poly(N-isopropylacrylamide) (PNIPAM), and thus shows improved oxygen reduction activity and durability as compared to conventional catalysts supported on carbon.
