Development of heterogeneous catalysts for hydrogen production from ammonia borane and investigation of reaction kinetics

In this study, copper (0) nanoclusters on carbon was formed by the reduction of the copper (II) salt in the aqueous phase by using suitable reductants after suppated on the surface. Experimental method for the preparation of copper (0) nanoclusters; particle size, temperature, solvent and reductive parameters. The solid catalytic material obtained was as a result of the processes carried out can be selected from the group consisting of inductively coupled plasma-optical emission spectroscopy (ICP-OES), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), powder X-ray diffraction (P- XRD) The catalytic activity of the Cu(0) nanoparticles was determined in the active carbon structure and the kinetics of the ammonia-borane hydrolysis reaction in the presence of the Cu/C catalyst were investigated with different catalyst and substrate concentrations and temperature. The rate expression and activation parameters (Arrhenius activation energy (Ea), activation enthalpy (ΔH#) and activation entropy (ΔS#) values) of the hydrolysis reaction of ammonia-borane were calculated using the kinetic data obtained.
