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.

In this work, a synthesis method of residue-free PdPt nanodendrites on reduced graphene oxide (rGO) is reported. Using UV light as an energy trigger and methanol as the reducing agent, PdPt nanodendrites are synthesized with clean, residue-free surfaces (e.g., surfactant and polymer). In comparison with commercial Pd/C and Pt/C catalysts, the as-prepared PdPt nanodendrites on rGO have a large electrochemically active surface area, enhanced catalytic activity, high stability, and tolerance toward the ethanol oxidation reaction in alkaline media. Among the nanodendrite composites prepared, those containing a Pd:Pt ratio of 1:2 on rGO exhibit the best stability and durability, and their mass activity is 2.0 and 2.4 times greater than those of commercial Pt/C and Pd/C catalysts, respectively. This strategy presents an environmentally friendly way to fabricate other noble metal catalysts with improved catalytic activity and stability for use in direct alcohol fuel cells.
