Negligible overpotential for HER: The front cover artwork was chosen to represent a 3D Ni–Mo electrocatalyst with negligible overpotential for the alkaline hydrogen evolution reaction (HER). The 3D nanoporous Ni–Mo electrocatalyst was fabricated and investigated for alkaline HER. On page 1138, Prof. P. B. Wan et al. show how they synthesized the electrocatalyst with well-controlled composition, desired dimensions, and nanoporosity to exhibit improved HER performance with low overpotential, high current density, ultrahigh activity, and durable stability, challenging that of Pt/C catalyst.
