Non-linear kinetic analysis of catalytic hydrolysis of ethylenediamine bisborane with nano-structured Pd/TiO2 catalyst

In this study, the hydrogen generation from catalytic hydrolysis of ethylenediamine bisborane (EDAB) solution catalyzed by nanostructured titanium dioxide (TiO 2 ) supported Pd metallic catalyst was carried out. TiO 2 support material was synthesized by the sol-gel method from titanium (IV) ethoxide. Pd was loaded into TiO 2 by the conventional impregnation-reduction method and reduction was carried out at 750 °C in an H 2 atmosphere. The characterization of catalysts was done with SEM-EDX and multi-point BET analysis. To investigate the hydrogen production by catalytic hydrolysis of EDAB, parameters such as Pd loading (2–4% by weight) and temperature (40–80 °C) were chosen in the presence of ethylenediamine bisborane aqueous solution (0.034% by weight). Detailed non-linear kinetic analysis was applied to the experimental data by considering and Langmuir-Hinshelwood model and power law. The activation energy E a was calculated as E a = 33.61 kJ mol −1 and E a = 36.32 kJ mol −1 according to Langmuir-Hinshelwood and power-law model respectively for the Pd/TiO 2 catalyst. • Hydrolysis of Ethylenediamine Bisborane was investigated. • EDAB is a material that can chemically store and release hydrogen safely and efficiently. • Nano-Structured Pd/TiO 2 Catalyst was synthesized. • Non-Linear kinetic analysis was performed for hydrolysis reactions.
