Pd nanoparticles supported on MIL-101 as high-performance catalysts for catalytic hydrolysis of ammonia borane

•Ultrafine Pd NPs have been immobilized in the framework of MIL-101.•Pd@MIL-101 exhibit the highest catalytic activity among Pd-based catalysts.•The Pd@MIL-101 shows good durable stability.

Well dispersed ultrafine Pd NPs have been immobilized in the framework of MIL-101, and tested for the catalytic hydrolysis of ammonia borane. The powder XRD, N2 adsorption–desorption, TEM, and ICP-AES were employed to characterize the Pd@MIL-101 catalyst. The as-synthesized Pd@MIL-101 exhibit the highest catalytic activity toward hydrolysis of AB among the Pd-based nano-catalysts ever reported, with the TOF value of 45 mol H2 min−1 (mol Pd)−1.
