Operando reactors are used to study, qualitatively and/or quantitatively, active sites of the catalyst and the intermediates of a catalytic heterogeneous chemical reaction, while the reaction is being carried out ("in situ, on-line catalysis studies").

In the present work, an operando reactor using transmission infra-red (IR) absorption spectroscopy has been used to study the Fischer-Tropsch reaction between carbon monoxide (CO) and hydrogen (H2) with main products methane (CH4) and water on a Co/SiO2 catalyst.
