Description:
(abstract)Alternative strategies to design sustainable-element-based electrocatalysts enhancing oxygen evolution reaction (OER) kinetics are demanded to develop affordable yet highperformance waterelectrolyzers for green hydrogen production. Here, it is demonstrated that the spontaneous-spin-polarized two-dimensional π-d conjugated framework comprising abundant elements of nickel and iron with a ratio of Ni:Fe =1:4 with benzenehexathiol linker (BHT) can improve OER kinetics by its unique electronic property. Among the bimetallic NiFex:y-BHTs with various ratios with Ni:Fe = x:y, the NiFe1:4-BHT exhibits the highest OER activity. The NiFe1:4-BHT shows a specific current density of 140 A/g at the overpotential of 350 mV.
