CuO-Fe2O3 Nanoparticles Supported on SiO2 and Al2O3 for Selective Hydrogenation of 2-Methyl-3-Butyn-2-ol

In this study, novel SiO2- and Al2O3-supported Cu-Fe catalysts are developed for selective hydrogenation of 2-methyl-3-butyne-2-ol to 2-methyl-3-butene-2-ol under mild reaction conditions. TEM, XRD, FTIR studies adsorbed CO TPR-H2 performed characterize the morphology, nanoparticle size, particle distribution, as well electronic state deposited metals in prepared catalysts. The deposition Fe Cu metal particles on aluminum oxide carrier results formation a mixed phase with strong interaction between precursors during calcination. highly dispersed nanoparticles Fe2O3 partially reduced CuOx, an average size 3.5 nm contact interactions 5Cu-5Fe/Al2O3 catalysts, provide high selectivity 93% toward at complete conversion unsaturated alcohol.
