Abstract

Epoxy-activated acrylic particulate polymer, namely Eupergit CM, supported Co-Fe-Ru-B catalyst (EP/Co-Fe-Ru-B) for the first time was used to produce H-2 from hydrolysis of NH3BH3. The EP/Co-Fe-Ru-B showed very effective performance in the production of H-2 from the hydrolysis of NH3BH3. Various techniques such as XRD, SEM-EDS, ICP-OES, and TEM have been used to characterize these catalysts. The parameters on the hydrolysis reaction of NH3BH3 such as the effect of metal amount, the effect of Ru percentage, the effect of NH3BH3 concentration, the effect of NaOH concentration, the amount of catalyst, temperature, and catalyst durability were investigated in detail. Eupergit CM based poly-mer support and Ru particles have been found to be highly effective in H-2 production re-actions. The hydrogen production rate (HGR) of the EP/Co-Fe-Ru-B catalyst was found to be 36,978 mL/min/g(cat), which was quite good compared to the values reported in the literature. In addition, the activation energy (Ea) of the polymer-supported Co-Fe-Ru-B catalyst was determined as 24.91 kJ/mol. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
