An unprecedented type of Hf-doped silica nanotubes was synthesized using a straightforward one-pot sol-gel procedure. The well-defined nanotubes with a diameter of 14-20 nm exhibited high sp. surface area and a widely open texture. The method – involving a key pH adjustment step – allowed a quant. insertion of hafnium in the materials (Si/Hf = 74) and favored the insertion of Hf as dispersed species. Depending on the synthesis parameters, the chem. environment around Hf was modified, as evidenced by XPS, NH3-TPD and NH3-IR. Hf-doped silica nanotubes showed excellent activity in the conversion of glycerol to solketal, a reaction of high relevance in the context of biorefineries. Importantly, the turnover frequency and the acidity were unambiguously correlated with the insertion of Hf in the silica matrix. The best catalyst was proven to be stable and recyclable, and this sustainable reaction was also amenable to further catalytic enhancement upon optimized reaction conditions. In the experiment, the researchers used many compounds, for example, (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol (cas: 100-79-8Name: (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol).
(2,2-Dimethyl-1,3-dioxolan-4-yl)methanol (cas: 100-79-8) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Name: (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol
