Magnetically isolable Pd(0) nanoparticles supported on surface functionalized Fe 3 O 4 for hydrogen generation via ammonia borane hydrolysis
Pd(0) nanoparticles supported on surface functionalized magnetite (Fe 3 O 4 /SiO 2 ‐NH 2 /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,...

/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 (E
