The correlation between the surface reconstruction of AgPdF and AgPd nanoalloys and their catalytic activity and stability in FOR is examined. AgPdO is reconstructed to form AgPd, whilst AgPdF maintains a record retention time of up to 78 hours and a higher current density.

In this work, 20% Pt-Fe3O4/MWCNT (Pt:Fe3O4 weight ratio of 80:20) and 20% Pt/MWCNT nanoparticles were synthesized and characterized as anode electrocatalysts in H2SO4 media. First, the electrocatalyst were submitted to accelerated catalyst degradation test (ACDT) by performing 500 cycles between 0.6 and 1.2 V (vs. SHE). Then, their performance for the EOR was evaluated. The magnetite-containing nanoparticles demonstrated to be highly electrochemically stable, with negligible surface area losses (less than 7%) in thehydrogen adsorption/desorption region. Moreover, Pt-Fe3O4/MWCNT showed a significantly enhanced catalytic activity for the EOR when compared to Pt/MWCNT, with almost 46% increase in current density when using Fe3O4 as co-catalysts.
