The overall result is the chemical fixation of carbon dioxide. A Zn/MCM-41(im) catalyst prepared by a wet impregnation method exhibited excellent activity for the reaction of glycerol and urea with 75% glycerol conversion and 98% selectivity to GC. Such excellent activity of the catalyst is explained based on the presence of both basic and acidic sites on the same catalyst which activates the glycerol and urea molecules, respectively.</p>1 aKondawar, S., E.1 aPotdar, A., S.1 aRode, C., V.  uhttps://library.ncl.res.in/content/solvent-free-carbonylation-glycerol-urea-using-metal-loaded-mcm-41-catalysts
