a–d, MOR CV evolutions (a), MOR mass activity evolutions (b), HER LSV evolutions (c), and HER mass activity evolutions (d) for Pt/C, PtT-2.8 and PtT-2.8-6 nm. The accelerated durability tests show 6% activity loss for PtT-2.8 toward MOR after 20,000 potential cycles and 12% activity loss for PtT-4.7 toward HER after 10,000 potential cycles, both surpassing Pt/C. e, Atomic ratio of Pt:Pd before and after the durability tests for PtT-2.8 and PtT-4.7, showing negligible compositional changes. f, g, TEM images, HAADF-STEM images, and lattice profiles of PtT-2.8 (f) and PtT-4.7 (g) after the durability tests, showing negligible structural changes.
