Abstract
Back cover image: Large-scale green hydrogen production technologies play an important role in replacing fossil fuels. However, its cost heavily relies on non-precious metal electrocatalysts with high activity and stability under industrial conditions. In article number CEY2684, Pan et al. fabricated a Fe and Co co-incorporated nickel (oxy) hydroxide exhibits outstanding OER performance under industrial conditions. The surface-reconstructed γ-NiOOH with high valence state is the active layer, where the optimal (Fe, Co) co-incorporation tunes its electronic structure, change the potential determining step, and reduces the energy barrier, leading to ultra-high activity and stability.
