Abstract / Description:Microcalorimetric methods, carried out under reaction conditions, provide insight into the interaction of adsorbates with the active surfaces, therefore, contributing to shade light on the nature of the active sites. In particular, the thermal effects during the chemisorption of a reactant over a solid under reaction condition provide information about the strength of the chemical bonds involved in the adsorption process and the transformations taking place as consequence of the adsorption process. In this work, microcalorimetry is applied to probe the active surface of CNF based materials for heterogeneously catalyzed and electro-catalyzed reaction.
In comparative study on differently active materials, a critical analysis of the reactivity data can be delineated with respect to the surface processes occurring under good catalyst performance. Two systems have been studied: O2 chemisorption at reaction temperature on Pd nanoparticles/CNF based catalyst for the selective oxidation of alcohol to valuable compounds; CO2 chemisorption at reaction temperature on Fe/CNFs based electrocatalysts used for the reduction of CO2 to long chain hydrocarbon.
