The catalytic data indicate that the catalysts are active in the conversion of glycerol, promoting not only the typical dehydration but also its hydrogenolysis without an external source of hydrogen, resulting in the production of significant amounts of ethylene glycol and methanol. Partially frameworkattached (Si─O)2Zr═O species were identified and are suggested to play an important role in the catalytic behavior of these materials.engjournal article2026-05-13cv-prod-503355310.1002/cctc.707711867-3899
