Not noble but effective: A new class of heterogeneous hydrogen-evolving electrocatalysts based on inexpensive components was developed. The carbon-supported nickel–molybdenum nitride (NiMoNx, see picture) catalyst had a nanoscale sheet structure comprising a few layers and an abundance of highly accessible reactive sites.
