Keywords:
Cobalt, Bead, NaBH4, HydrogenAbstract
Cobalt-doped bead type catalyst was synthesized for hydrogen generation from sodium borohydride hydrolysis reaction by using sodium hydroxide. Synthesized catalyst was characterized using XRD (X-ray diffraction), nitrogen adsorption/desorption isotherm and FTIR (Fourier transforms infrared) analyses techniques. XRD pattern showed presence of chitosan in the structure, while cobalt species were not observed. Nitrogen adsorption/desorption isotherm was exhibited a behavior indicating of micro-mesoporous structure. The surface area, total pore volume and pore diameter values of catalyst were determined as 35.0 m2/g, 0.03 cm3/g and 3.4 nm, respectively. FTIR spectra showed existence of peaks related to chitosan. The catalyst was test in sodium borohydride hydrolysis reaction and hydrogen production rate was determined as 28 mL. min-1. g-1.
