In this study, a highly stable chromium-free catalyst Co3AlOx was prepared for the synthesis of furfuryl alcohol. The catalyst exhibited excellent catalytic activity and stability, enabling efficient hydrogenation of furfural to furfuryl alcohol.
Furfuryl alcohol (FFA) is an important organic chemical for the chemical industry, however, an efficient chromium-free catalyst with high stability is still expected. Herein, a Co3AlOx catalyst was successfully prepared for the synthesis of FFA via the furfural (FF) hydrogenation, which exhibited excellent stability and catalytic activity with a FFA yield of 96.2 %. The Co2+ species significantly promoted the formation of the oxygen vacancy on the surface of Co3AlOx, which favored the adsorption and activation of H-2, The Co3+ species provided anchors for the adsorption of the aldehyde group in FF. The selective adsorption of FF via the O-terminal of the aldehyde group in a vertical or tilted configuration on the surface of Co3AlOx ensured the efficient hydrogenation of FF to FFA.
