dc.description.abstract | [EN] The catalytic activity of metal-organic frameworks (MOFs) depends largely on the presence of structural defects. In the present study, cobalt based metal-organic framework TMU-10, [Co-6(oba)(5)(OH)(2)(H2O)(2)(DMF)(4)](n)center dot 2DMF has been subjected to controlled thermolysis under air atmosphere at different temperatures in the range of 100-700 degrees C. This treatment results in the removal of ligands, and generation of structural defects and additional porosity in a controlled manner. The resulting materials, denoted as quasi MOFs according to the literature, were subsequently employed as catalysts for hydrogen release from NaBH4 by hydrolysis. The quasi TMU-10 framework obtained at 300 degrees C (QT-300) shows the highest turnover frequency of the series with a value of 13 333 mL min(-1) g(-1) at room temperature in the absence of a base, with an activation energy of 56.8 kJ mol(-1). The simultaneous presence of micro- and mesopores in QT-300 with unsaturated Lewis acid sites on cobalt nodes due to the conversion of a fraction of Co(ii) centers to Co(iii) as well as the presence of tetrahedral Co(ii) sites is responsible for this catalytic behavior. The influence of the catalyst dosage and BH4- concentration is in good agreement with the Langmuir-Hinshelwood model in which both reactants must be adsorbed onto the catalyst surface. Further investigation on the hydrolysis of the NaBH4 + D2O system presents a primary kinetic isotope effect indicating that water O-H bond cleavage occurs in the rate determining step. | es_ES |
