Multi-walled carbon nanotube supported rhodium nanoparticles as a catalyst in the production of hydrogen from the hydrolysis of dimethylamine-borane and investigation of reaction kinetics

In this master thesis, a new catalytic material was prepared and characterized that produced hydrogen from the hydrolysis of dimethylamine-boran (DMAB), which is considered an important amine-borane derivative. For this purpose, multi-walled carbon nanotube (MWCNT) supported Rh (0) nanoclusters were prepared ex-situ and their catalytic performance in hydrogen production by hydrolysis reaction from DMAB was investigated. Prepared MWCNT supported Rh (0) nanoclusters were charcaterized by using advanced analytical and spectroscopic methods such as inductively coupled plasma optical emission spectroscopy (ICP-OES), powder X-ray diffraction (P-XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), transmission electron microscopy-energy dispersed X-ray spectroscopy (TEM/EDX), high resolution transmission electron microscopy (HRTEM) and 11B-NMR. After analyzing the reusability performances of the prepared Rh (0) nanoclusters by hydrolysis from DMAB, the activation parameters (Ea: Activation Energy; ΔH#: Activation Enthalpy; ΔS#: Activation Entropy) were calculated by performing catalytic reactions at different temperatures.
