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.

Pt-Ni alloy nanocrystals with controlled architectures (multi-arms and flowers) have been synthesized via a simple colloid chemistry method. The crystal surfaces possess abundant low-coordination defect sites, where the reaction kinetics of methanol oxidation can be improved, resulting in the catalysts exhibiting better stability and higher resistance to poisoning.
