A near solvent-free synthetic route for Ce-UiO-66 metal-organic frameworks (MOFs) is presented. The MOFs are obtained by simply grinding the reagents, cerium ammonium nitrate (CAN) and the carboxylic linkers, in a mortar for few minutes with the addition of a small amount of acetic acid (AcOH) as modulator (8.75 eq, o.5 mL). The slurry is then transferred into a 2 mL vial and heated at 120 °C for 1 day. The MOFs have been characterized for their composition, crystallinity and porosity and employed as heterogeneous catalysts for the photo-oxidation reaction of substituted benzylic alcohols to benzaldaldehydes under near ultraviolet light irradiation. The catalytic performances, such as selectivity, conversion and kinetics, exceed those of similar systems studied by chemical oxidation using similar Ce-MOFs as catalyst. Moreover, the MOFs were found to be reusable up to three cycles without loss of activity. Density functional theory (DFT) calculations were used in order to fully describe the electronic structure of the best performing MOFs and to provide useful information on the catalytic activity experimentally observed. 8 ASSOCIATED CONTENT Supporting Information available.

“…In addition to the above several widely used synthetic methods, other methods have recently emerged, such as mechanochemical synthesis, 43 heating reflux method, 44,45 sonochemical synthesis and so on. 46,47 The mechanochemical method is a rapid, efficient, and solvent free method and refers to the use of mechanical external forces (such as extrusion, grinding, shearing, etc.)…”

“…The method here presented is definitely innovative in the field of Ce-MOFs synthesis: it is solvent-free (except for washes) and it uses a minimum quantity of acetic acid to obtain the products, unlike recently reported works. 26,27 Besides, to the best of our knowledge, Ce-UiO-66-Br was obtained here for the first time. X-Ray Powder Diffraction (XRPD) patterns (Figure 1) show the typical UiO-66 fcu phase peak positions at about 7.1° and 8.2°of 2θ, which correspond to the lattice planes (111) and (002),respectively.…”

<div> <p>A novel solvent-free synthesis for Ce-UiO-66 metal-organic frameworks (MOFs) is presented. The MOFs are obtained by simply grinding the reagents, cerium ammonium nitrate (CAN) and the carboxylic linkers, in a mortar for few minutes with the addition of a small amount of acetic acid (AcOH) as modulator (1.75 eq, o.1 ml). The slurry is then transferred into a 1 ml vial and heated at 120°C for 1 day. The MOFs have been characterized for their composition, crystallinity and porosity and employed as heterogenous catalysts for the photo-oxidation reaction of substituted benzylic alcohols to benzaldaldehydes under near ultraviolet light irradiation. The catalytic performances, such as yield, conversion and kinetics, exceed those of similar systems studied by chemical oxidation and using Ce-MOF as catalyst. Moreover, the MOFs were found to be reusable up to three cycles without loss of activity. Density functional theory (DFT) calculations gave an estimation of the band-gap shift due to the different nature of the linkers used and provide useful information on the catalytic activity experimentally observed.</p> </div>
