Hydrogenation of carbon monoxide over nanostructured systems: A mechanochemical approach

► We investigated the mechanochemical hydrogenation of CO over nanostructured FeCo- and Mg2Ni-based catalysts. ► We developed a methodology to evaluate the activity of the solid catalysts on an absolute basis. ► Conversion data were, indeed, expressed as turnover frequency, TOF. ► Conversion was related to the ball to powder collisions events through the mechanochemical turnover frequency parameter, MTOF.
