3D-Printed Fe/γ-AlO Monoliths from MOF-Based Boehmite Inks for the Catalytic Hydroxylation of Phenol.

The synthesis of dihydroxybenzenes (DHBZ), essential chemical reagents in numerous industrial processes, with a high degree of selectivity and yield from the hydroxylation of phenol is progressively attracting great interest in the catalysis field. Furthermore, the additive manufacturing of catalysts to produce 3D printed monoliths would provide additional benefits to enhance the DHBZ synthesis performance. Herein, 3D cellular Fe/γ-AlO monoliths with a total porosity of 88% and low density (0.
