| 1 | Ternary Ni-Co-Fe oxyhydroxide oxygen evolution catalysts:Intrinsic activity trends,electrical conductivity,and electronic band structure显示文摘Nickel-,cobalt-,and iron-based(oxy)hydroxides comprise the most-commonly studied electrocatalysts for the oxygen-evolution reaction(OER)in alkaline solution.A fundamental understanding of composition-structure-activity relationships for mixed-metal Ni-Co and Ni-Co-Fe(oxy)hydroxides is important to guide the design of advanced OER catalysts.Here we use cyclic voltammetry,chronopotentiometry,inductively-coupled plasma-optical emission spectroscopy,and in situ electrical conductivity measurements to characterize the properties and activity of various compositions of Ni-Co-Fe(oxy)hydroxides prepared by cathodic co-electrodeposition.Consistent with previous studies,we find Fe is essential for the mixed-metal(oxy)hydroxides to achieve high OER activity.In the rigorous absence of Fe(achieved by using specially cleaned electrolytes),the most-active Ni-Co(oxy)hydroxide composition has an OER turn-over frequency only twice that ofpure Co(oxy)hydroxide,suggesting minimal synergism between the two metals.The addition of Co to Ni-Fe(oxy)hydroxides shifts the onset of electrical conductivity to lower potentials,but has little effect on the intrinsic OER activity,with the most-active Ni-Co-Fe(oxy)hydroxide having an OER turn-over frequency only -1.5 times that of the Ni-Fe(oxy)hydroxides.The magnitudes of the electrical conductivities are similar for all the compositions measured.Density-functional-theory-calculated projected density of states show a significant contribution of all chemical elements at the valence band edge of the mixed-metal oxyhydroxide electronic structure,demonstrating significant electronic hybridization between the elements.The calculations suggest the involvement of all the elements in modulating the electronic structure at putative Fe-based active sites that are probably located at edges or defects in the two-dimensional oxyhydroxide sheets. | Michaela Burke Stevens Lisa J.
