In this work, we demonstrate that Hf-MOF-808 can be prepared from a material with a higher amount of Bronsted acid sites, via modulated hydrothermal synthesis, to a material with a higher proportion of unsaturated Hf Lewis acid sites, via modulated solvothermal synthesis. The Lewis/Bronsted acid properties of the resultant metallic clusters have been studied by different characterization techniques, including XAS, FTIR and NMR spectroscopies, combined with a DFT study. The different nature of the Hf-MOF-808 materials allows their application as selective catalysts in different target reactions requiring Lewis, Bronsted or Lewis-Bronsted acid pairs.Reconocimiento - No comercial (by-nc)QUIMICA ORGANICAArtículo10.1039/d1sc02833bAbierto34349973PMC8317639
