Abstract

Exploring nonprecious metal based catalysts to replace noble metal based catalysts for hydrolysis of ammonia borane (NH3BH3, AB) is still an ongoing challenge. In this work, low-cost ternary nickel–iron–phosphide catalysts supported on Ni foam (Ni–Fe–P/Ni foam) have been synthesized by one-step electroless plating and the as-prepared Ni–Fe–P catalysts were homogeneously distributed on the nickel network. Compared with the binary Ni–P/Ni foam and Fe–P/Ni foam synthesized in the same way, the ternary Ni–Fe–P/Ni foam exhibited the best catalytic activity at room temperature. By using Ni–Fe–P/Ni foam catalysts with a concentration of 0.5 wt% AB, a hydrogen generation (HG) rate of 0.7 L min−1 g−1 could be achieved at 30 °C with a relatively low activation energy value of 42.0 kJ mol−1. These results indicated that the ternary Ni–Fe–P/Ni foam is a very promising catalyst due to its low-cost and acceptable catalytic activity.
