Ultrafine PtCo alloy nanoparticles integrated into porous N-doped nanosheets for durable oxygen reduction reaction

Abstract

Here, we propose a sub-3 nm small-size PtCo alloy catalyst integrated into a porous nitrogen-doped nanosheet through a space-confined and interfacial induction strategy. The designed PtCo–CoNC–P catalyst exhibits exceptional durability, with only a minimal 2 mV decline in half-wave potential after 30 000 cycles of accelerated durability tests.
