Fabrication of Al2O3-ZrO2 composite catalysts with tunable acid-base properties for highly efficient aldol condensation of furfural with acetone

A series of alumina-zirconia composite catalysts were fabricated via a homogeneous two-step solution-phase strategy and employed in the aldol condensation of furfural with acetone to produce furfurylidene acetone (FAc). It was demonstrated that after tuning the surface acid-base properties of Al2O3-...

Summary:A series of alumina-zirconia composite catalysts were fabricated via a homogeneous two-step solution-phase strategy and employed in the aldol condensation of furfural with acetone to produce furfurylidene acetone (FAc). It was demonstrated that after tuning the surface acid-base properties of Al2O3-ZrO2 composites by varying the Al content, a superior catalytic performance (Al/(Al + Zr) ratio of 0.5) with a FAc yield of larger than 90.0% compared to single metal oxides and other mixed metal oxides reported was obtained. [Display omitted] •Bifunctional Al2O3-ZrO2 composite catalysts were constructed.•Surface acid-base properties of Al2O3-ZrO2 composites changed with the Al content.•Such composites were highly active for aldol condensation of furfural with acetone.•Surface acid-base cooperative effect contributed to high catalytic efficiency.
