ChemistrySelect, 8(31). doi: 10.1002/slct.2023020352365-6549https://doi.org/10.1002/slct.202302035https://hdl.handle.net/20.500.12428/5534Pd(0) nanoparticles supported on surface functionalized magnetite (Fe3O4/SiO2-NH2/HB@Pd) were prepared as catalyst for hydrolysis of ammonia borane (AB). The obtained magnetic nanocomposite material was seperated from the reaction media through a permanent magnet and characterized by FT-IR, XRD, SEM-EDX, TEM, ICP-OES and XPS techniques. 100 mg Fe3O4/SiO2−NH2/HB@Pd nanocomposite with Pd metal content of 6.00±0.14 catalyzed the hydrolysis of 10 mM AB at 25 °C with 100 % yield. The presented work includes the effect of catalyst amount and temperature on the rate of the hydrolysis reaction of AB. As a result of the kinetic studies, the activation energy (Ea) for the Fe3O4/SiO2−NH2/HB@Pd catalyzed AB hydrolysis reaction was calculated as 34±1 kJ.mol−1, and the TOF value was calculated as 133 mol H2.(mol Pd(0).h)−1. The designed heterogenous magnetic nanocomposite catalyst demonstrated significant catalytic activity for AB hydrolysis reaction at 25 °C.eninfo:eu-repo/semantics/closedAccessAmmonia boraneHeterogenous catalystHydrogenMagnetitePd nanoparticlesArticle83110.1002/slct.202302035Q3WOS:0010491015000012-s2.0-85168486559
