High dispersion Pt nanoparticles supported on 2D Ti3C2X2 (X = OH, F) nanosheets are presented and electro-chemical measurements confirm that the Pt/Ti3C2X2 catalyst shows enhanced durability and improved ORR activity compared with the commercial Pt/C catalyst.
The surface modified Ti 3 AlC 2 supported Pt (Pt/e-TAC) catalyst shows improved activity and enhanced stability toward the oxygen reduction reaction when compared with the commercial Pt/C catalyst.
