Leyla Najafi, Sebastiano Bellani, Andrea Castelli, Milena P.This article is cited by 29 publications. The Tafel plot for the catalyst demonstrated a slope of ∼37 mV/decade, indicating a Heyrovsky-type rate-limiting step in the observed HER. High durability has been assessed by cyclic and linear sweep voltammetry, as well as controlled potential electrolysis techniques. Its mass activity (1.13 A/mg Pt) surpasses that of commercial Pt/C (∼0.38 A/mg Pt) at the overpotential of 100 mV. ![]() The prepared catalyst platform demonstrated large current density (100 mA/cm 2) at 122 mV applied overpotential for the hydrogen evolution reaction (HER), with measured Faradaic efficiency of 97(☑)%. This approach stands out, as compared to Pt monolayer deposition techniques atop metal foams, or a recently reported atomic layer deposition (ALD), as a way of depositing submonolayer coverage of precious catalysts within the 1–10 nm pores found in microporous solids. Immediately upon electrochemical reduction of the Pt(II/IV), metallic Pt (most likely atomistic Pt) was observed. ![]() The XPS analysis of sample impregnated with Pt ions confirmed the presence of Pt(II/IV) species and did not show any signs of metallic nanoparticles, as further confirmed by transmission electron microscopy. The pyrimidine porous-organic polymer (PyPOP) was selected because of the abundant Lewis-base binding sites within its backbone, to be combined with graphene to produce the composite that was shown to uptake Pt ions simply upon brief incubation in H 2PtCl 6 solution in acetonitrile. A facile, postsynthetic treatment of a designed composite of pyrimidine-based porous-organic polymer and graphene ( ) with ionic Pt, and the subsequent uniform electrodeposition of Pt metallic within the pores, led to the formation of a composite material ( ). ![]()
