Dehydrogenation of hydrazine hydrate using nico bimetallic catalyst supported on natural zeolite (Za), z-nay, z-hy, al2o3 and tio2

Hydrogen can be produced by dehydrogenation reaction of hydrazine hydrate with help of catalyst material. This study aims to investigate the effect of different catalyst support which is loaded with NiCo bimetallic catalyst toward the dehydrogenation reaction of hydrazine hydrate. Catalyst characterization was carried out using XRD, SAA, and XRF. The catalyst obtained was tested for its catalytic activity through the dehydrogenation reaction of hydrazine hydrate. Surface area analysis was performed for natural zeolite, zeolite NaY, zeolite HY with the value of 40.99 m²/g, 88.94 m²/g, 162.12 m²/g, respectively. NiCo metal alloys impregnated on ZA, Z-NaY, Z-HY, Al₂O₃, and TiO₂ supports produce diffraction patterns at angles of 44.5°, 51.7° and 76.3° with low intensity. The surface area decreases after the NiCo was impregnated on the catalyst support. NiCo(1:3)/TiO₂ catalyst produced the maximum conversion and the best catalyst activity which is 29.71 % for ± 5 minutes with a TOF of 357.79 h^-1 and activation energy of 47.33 kJ/mol.
