Benzyl alcohol oxidation on MnFeCoNiCu-PBA reaches 100 mA cm-2 at a lower potential than OER and improves hydrogen generation.
Caveat: Hydrogen production absolute amounts are only plotted in Figure 3d and not tabulated in main text.
15763; 15767 · Abstract; Electrochemical Performance · Figure 3b-d · Linked to 3 structured results
MnFeCoNiCu-PBA converts benzyl alcohol to benzoic acid with high conversion, 100% selectivity and 98.9% Faradaic efficiency at 1.48 V vs RHE over 4 h.
Caveat: NMR confirmation and chronoamperometry are provided in SI Figures S13-S14; product quantification is reported in the main text.
15767 · Electrochemical Performance · Figure 3c; Figures S13-S14 · Linked to 3 structured results
Successive introduction of Co, Ni and Cu into MnFe-PBA improves OER and BA oxidation activity through synergistic effects, larger active surface area and improved charge transfer/electronic conductivity.
Caveat: Electronic conductivity is claimed in the abstract/conclusion but quantified only indirectly by EIS; the SI does not tabulate numeric Rct values.
15767-15768 · Electrochemical Performance · Figures S16-S17 · Linked to 10 structured results
During benzyl alcohol oxidation the multimetallic PBA precursor reconstructs into mixed metal hydroxide/(oxy)hydroxide nanosheets that act as the active catalyst.
Caveat: Post-reaction assignment is based on ex situ IR/PXRD/SEM/TEM/EDX/XPS after BA oxidation, not operando structure.
