Abstract:
A P-doped PtNi alloy loaded on N,C-doped TiO 2 nanosheets (P–PtNi@N,C–TiO 2 ) exhibited excellent activity and durability for the oxygen reduction reaction (ORR) in 0.1 M HClO 4 solution with mass (4×) and specific (6×) activity several times higher than those of commercial 20 wt% Pt/C, respectively. The P dopant mitigated the dissolution of Ni and strong interactions between the catalyst and the N,C–TiO 2 support inhibited catalyst migration. This provides a new approach for the design of high-performance non-carbon-supported low-Pt catalysts to be used in harsh acidic environments.
