The development of active, selective, and robust catalysts is a key issue in promoting the practical application of hydrazine monohydrate (N₂H₄⋅H₂O) as a viable hydrogen carrier. Herein, the synthesis of a supported Ni–Pt bimetallic nanocatalyst on mesoporous ceria by a one‐pot evaporation‐induced self‐assembly method is reported. The catalyst exhibits exceptionally high catalytic activity, 100 % selectivity, and satisfactory stability in promoting H₂ generation from an alkaline solution of N₂H₄⋅H₂O at moderate temperatures. For example, the Ni₆₀Pt₄₀/CeO₂ catalyst enabled complete decomposition of N₂H₄⋅H₂O to generate H₂ at a rate of 293 h⁻¹ at 30 °C in the presence of 2 M NaOH, which compares favorably with the reported N₂H₄⋅H₂O decomposition catalysts. Phase/structural analysis by XRD, TEM, and Auger electron spectroscopy was conducted to gain insight into the excellent catalytic performance of the Ni–Pt/CeO₂ catalyst.
