dc.description.abstractThis study presents experimental and theoretical results on the role of the catalytic effect by ruthenium added titriplex (R) (R) III Carbon Quantum Dots (CQD) support material in the hydrolysis of ammonia borane for H2 2 duction. H2 2 production was achieved under different reactant conditions (in variable amounts of catalysis, ruthenium, NaOH, ammonia borane and at various temperature). Since the experimental results and theoretical calculations which includes the effect of all electrical forces acting on valence electrons (overlap density tions, van der Waals forces, Covalent bonding and halogen bonds) are in very good agreement in the study, theoretical predictions are also made. By considering the rhodium element instead of the ruthenium element, performance of the titriplex support material was estimated to be approximately 30% more effective ruthenium. The NaOH molecule acts as a hydrolyzed water molecule with catalysis interaction and contributes the formation of oxidized boron. When NaOH is not present, the interaction time of the ammonia borane molecule with catalysis comes to the fore. This time is called threshold time. In molecular modeling, while almost all of the ammonia borane molecules contribute to H production, only 15% of the water molecules contribute this rate. However, while some of the released H atoms remains in the water, other parts observe to play a role the production of H2 2 and hydronium. The interaction rate of the water molecule increases with the increase the interaction surface of the catalyst. Any external effect that prevents the formation of hydronium and celerates the interaction of free H atoms with each other increases the efficiency. One of the predicted results this study is that the increased pressure shows separating role for hydronium.
