The synthesis of MWCNT supported nanoclusters and the reacti̇on ki̇neti̇cs for catalycti̇c hydrolysi̇s of hi̇drazi̇ne borane

In this study, we report the preparation, characterization and the investigation of the catalytic activities of MWCNT stabilized rhodium(0) nanoparticles in the hydrolysis of hidrazine-borane. The MWCNT stabilized rhodium(0) nanoparticles were prepared from the in-situ reduction of rhodium(III) chloride in the hydrolysis of hidrazine-borane at room temperature. The prepared rhodium(0) nanoparticles were isolated as solid materials and characterized by using inductively coupled plasma optical emission spectroscopy (ICP-OES), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS). The catalytic activity of MWCNT stabilized rhodium(0) nanoparticles and the kinetics of hydrogen generation from the hydrolysis of hidrazine-borane were studied depending on catalyst concentration, substrate concentration and temperature. The rate law and the activation parameters Arrhenius activation energy (Ea); activation enthalpy (ΔH#), and activation entropy (ΔS#), for catalytic hydrolysis reaction of hidrazine-borane were calculated from the obtained kinetic data.
