Electrochemical water splitting offers an appealing method to produce hydrogen as we attempt to achieve global carbon neutrality. However, the lack of earth-abundant, low-cost, active, and stable catalysts at large current densities severely hinders its industrial applications. TiNi3-based intermetallics as porous monolith catalysts (PMCs) exhibit an efficient hydrogen evolution reaction (HER) performance (an overpotential of 244 mV to afford 200 mA cm-2) and excellent stability in 1 M KOH. Theoretical calculations demonstrate that the synergetic effect between Ni and Mo can enhance HER activity. PMCs provide a new strategy to design catalysts with efficient and stable performance for industrial applications.
