WebMar 24, 2024 · Because of the larger lattice parameter of the Au core metal, the lattice spacing of the sole Pd shell at sub-nano scale would be expanded, leading to an upshift of its d-band center (Figure 6 B), in comparison with that of the pure Pd/C catalyst, which would strengthen the binding energy between CO-like species and Pd sites. 24, 27 After ... WebThe inherent ultrathin and porous features endow these PdFe catalysts with excellent electrocatalytic performance. As a result, the optimized 3D PdFe NCs show a much-improved methanol oxidation reaction (MOR) and ethanol oxidation reaction (EOR) activities in comparison with PdFe HNSs, Pd NPs, and commercial Pd/C catalysts.
