Highly dispersed Cu0-Cuδ+/MgO-FeOx catalyst for the synergistic enhancement of the hydrogenation of furfural
Cu-based catalysts are advantageous for selectively catalyzing the hydrogenation of the CO bonds in furfural (FF). Nevertheless, debates are ongoing regarding the identification of active sites. FeCuxMg catalysts were prepared using a hydrotalcite precursor. During the early stages of the reaction,...

| description | Cu-based catalysts are advantageous for selectively catalyzing the hydrogenation of the CO bonds in furfural (FF). Nevertheless, debates are ongoing regarding the identification of active sites. FeCuxMg catalysts were prepared using a hydrotalcite precursor. During the early stages of the reaction, the selective hydrogenation activity of the CO bond exhibited a volcano-shaped trend with increasing Cu content. FeCu0.15Mg showed the highest hydrogenation activity among all catalysts examined. In-situ X-ray diffraction (XRD), in-situ DRIFT, X-ray photoelectron spectroscopy (XPS) and other analytical techniques confirmed that Cu0-Cuδ+ sites assume a predominant role in catalytic reactions. At the optimal Cu/Fe ratio, the oxygen vacancies generated by FeOx facilitated the activation of the FF molecules. The highly dispersed Cu0-Cuδ+ sites served a crucial function in the activation of H2 and the rapid formation of reaction intermediates, significantly accelerating the reaction rate and process of FF hydrogenation. |
