DRIFTS spectroscopy enables the monitoring of molecular vibrations associated with changes in dipole moment, providing insights into adsorption modes of the reactants, the formation of reaction intermediates, and possible reaction mechanisms.<\/p>\n

In this first study, conducted by postdoctoral researchers \u00c9der Valdir and Morgana Rosset, along with PhD students Victor Albertini and Lucas Alves, a Fe\/HZSM-5 catalyst was investigated in the context of the Fischer\u2013Tropsch Synthesis reaction carried out at 10 bar \u2014 a process that converts synthesis gas (CO + H\u2082) into higher value hydrocarbons, such as olefins, gasoline, diesel, and sustainable aviation fuels.<\/p>\n

This marks another important step in the pursuit of efficient catalytic solutions for converting alternative carbon sources into sustainable products.<\/p>\n
