dc.description.abstractIn this study, firstly, piperazine bisborane (PBB) was synthesized and characterized as a solid hydrogen carrier material. Subsequently, a new catalytic system, agarose hydrogel@Ru (AGH@Ru), in which nanosized Ru0 particles were homogeneously dispersed and used as a catalyst for hydrogen production from the hydrolysis of PBB, was prepared. After the structural and morphological characterization of the catalyst, for the first time in the literature, catalytic hydrogen production from the hydrolysis of PBB was initiated. As a result of catalytic hydrolysis reactions conducted under different reaction conditions, it was determined that AGH@Ru achieved 100 % efficiency in the hydrolysis reaction and produced 6 mol of hydrogen per mole of PBB. The activation parameters for the hydrolysis reaction of PBB catalyzed by AGH@Ru were calculated as Ea = 74.95 kJ mol-1, Delta H# = 72.39 kJ mol-1, and Delta S# =-77.74 J mol-1 K-1. The AGH@Ru catalytic system, with a turnover frequency (TOF) of 3.24 min-1 or 194.4 h-1 at 25 degrees C, also exhibited excellent reusability.
