ABSTRACT
Abstract Structural and surface features of highly dispersed copper catalysts supported on hierarchical porous alumina were evaluated for the ethanol dehydrogenation reaction. The prepared by incipient wetness impregnation obtained a dual template sol–gel procedure. characterizations provided evidence that was in form monomeric octahedral Cu 2+ species adsorbed into an incomplete layer. A two‐step reduction observed temperature range 50–250 °C under H 2 /He flow. onset percentage + formed upon activation dependent loading. At lower loadings, amount increased, leading to slower less complete reduction. Based apparent energy turnover frequency, it could be concluded containing mixture /Cu 0 results more efficient catalyst than
