Surface Al leached Ti3AlC2 as a substitute for carbon for use as a catalyst support in a harsh corrosive electrochemical system†
Abstract
Surface Al leached Ti3AlC2 particles (e-TAC) with high corrosion resistance and excellent electrical conductivity were developed as an advanced support material for Pt catalysts. Electrochemical measurements confirm that the supported Pt/e-TAC electrocatalyst shows much improved activity and enhanced durability toward the oxygen reduction reaction when compared with the commercial Pt/C catalyst.
