Confining noble nanometal in zeolite framework is a promising way to improve its efficiency and durability for catalytic reactions. Herein, the synergistic effect of Pd nanoparticles and intrinsic acid sites in zeolite on promoting hydrogen generation performance is demonstrated. Pd nanoparticles are embedded into macroporous ZSM‐5 (designed as Pd@ZSM‐5) via a steam‐thermal strategy. The confined Pd and acid sites in Pd@ZSM‐5 synergistically promote the activation of ammonia borane (AB) and water molecules, resulting in the enhanced H 2 generation rates for AB hydrolysis. The interaction of Pd and acid sites in zeolite is further confirmed by solid‐state NMR techniques and the key aspect is the confinement effect of zeolite. Furthermore, Pd@ZSM‐5 shows high activity and durability in tandem hydrogenation of nitrobenzene.
