High CO tolerance of Pt nanoparticles synthesized by sodium borohydride in a time-domain NMR spectrometer. <b>International Journal of Hydrogen Energy</b>, v. 45, n. 43, p. 22973-22978, 2020.

This method consists of using sodium borohydride reducing agent assisted by magnetic field and radiofrequency pulses in the time-domain NMR spectrometer. This synthesis was useful to disperse the Pt nanoparticles over the carbon support and to compress the lattice strain of the Pt crystalline structure. Besides that, Pt/C MFP90° showed a multi-CO oxidation component in cyclic voltammetry, and this can avoid the poisoning effect by creating a large availability of CO species to be adsorbed, desorbed, and re-adsorbed. Pt/C MFP90° has also shown the best performance in the PEMFC regarding H2 and CO + H2 experiments.22973-22978openAccesscarbon compoundscarbon monoxideplatinumcarbonfuel cellsnanoparticlesborohydridessodium compoundsnmr spectranuclear magnetic resonanceArtigo de periódico434510.1016/j.ijhydene.2020.06.1050000-0001-8745-3421https://orcid.org/0000-0002-9287-607169.7888.50
