Abstract
Pumice-supported Ruthenium nanoparticles were prepared by the impregnation-reduction method and investigated for hydrogen production in the methylamine borane (MeAB) hydrolysis reaction. The catalytic properties of this highly active Ru/Pumice catalyst were analyzed in terms of temperature (from 298 K to 328 K), substrate ([MeAB]) amount, metal loadings ([Ru]), and recyclability. In addition, the characterization of the obtained catalyst was investigated by inductively-coupled plasma optical emission spectroscopy (ICP-OES), powder X-ray diffraction (P-XRD), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) imaging/spectroscopic techniques. The Ru/Pumice catalyst showed a superior initial TOF value (83.15 min-1 or 4989.30 h-1) in the MeAB hy-drolysis reaction, and also the activation parameters (Ea, til#, and tiS#) from the Arrhenius and Eyring-Polonyi equations were found to be 42.4 kJ/mol, 39.8 kJ/mol, and-110.07 J/ mol.K, respectively.(c) 2022 Hydrogen Energy Publications LLC.
