The synthesis of noble‐metal‐free recyclable catalysts with prominent catalytic performance for the complete hydrogen production from hydrazine borane (N 2 H 4 BH 3 , HB) is of great significance in achieving a hydrogen economy‐based society. Herein, Raney Ni is synthesized using a rapidly quenched aluminum–nickel alloy under a typical alkali leaching condition and is used to catalytically convert hydrogen of N 2 H 4 BH 3 to H 2 via hydrolyzing BH 3 groups and decomposing the N 2 H 4 moiety in alkaline conditions. It is the first report of a noble‐metal‐free catalyst achieving a complete production of hydrogen from N 2 H 4 BH 3 at room temperature. This noble‐metal‐free catalyst might tremendously broaden the actual utilization of HB as a promising chemical hydrogen storage material. In addition, such a simple strategy can also be expanded to design and synthesize other porous metals for more applications.
