Abstract With the development of renewable energy systems, clean hydrogen is burgeoning as an optimal alternative to fossil fuels, in which its application promising retarding global and environmental crisis. The evolution reaction (HER), capable producing high‐purity rapidly electrocatalytic water splitting, has received much attention. Abundant research about HER been done, focusing on advanced electrocatalyst design with high efficiency robust stability. As potential catalysts, metal nanoclusters (MNCs) have studied extensively. They are composed several a hundred atoms, sizes being comparable Fermi wavelength electrons, that is, < 2.0 nm. Different from atoms/nanoparticles, they exhibit unique catalytic properties due their quantum size effect low‐coordination environment. In this review, activity‐enhancing approaches MNCs applied electrocatalysis mainly summarized. Furthermore, recent progress classified different stabilization strategies, freestanding MNCs, organic, carbon supports, introduced. Finally, current challenges deficiencies these for prospected.
