520 _ _ |a Efficient and durable oxygen evolution reaction (OER) catalysts for alkaline water electrolysis are highly required for future energy storage and energy conversion devices. However, objective evaluation and fair comparison of different catalysts remain a challenge due to differencesin OER measurements. The evaluation criteria and the test protocol for the OER were investigated to compare the activity and stability of the electrocatalysts in the rotating disk electrode, and a standardized testing protocol was determined. In the past decades, significant progress has been made in improving the activity and durability of catalysts by developing new materials. In particular, NiFe layered double hydroxides (LDH) electrocatalysts have been developed. Here, we synthesized NiFe LDH with tunable Ni/Fe composition, which exhibits corresponding dependentmorphology, layer structure, and chemical states. The Ni3Fe LDH, resulting from the optimized local chemical environment with more oxygen coordination and ordered atomic structure, exhibits superior OER activity than most reported NiFe LDHs on both half cell and singlecell tests. In situ Raman spectra indicate the active species Ni(Fe)OOH at OER conditions and the dynamic phase transition during the cycling process. Different strategies have been applied to further modulate the structure and improve the catalytical performance of NiFe LDHs. Theintroduction of formamide and permanganate ions into the interlayer could modify the layer structure and enhance the stability to some extent, while hydrothermal treatment can increase the crystallinity and form well defined nanocrystal of NiFe LDH and other NiFe-based catalysts
