Fe/HY zeolite as an effective catalyst for levulinic acid production from glucose: characterization and catalytic performance

A series of Fe/HY zeolite catalysts with different FeCl3 weight percent (5, 10 and 15%) on HY zeolite have been synthesized in this study. All the catalysts were characterized by XRD, FESEM, N2 physisorption, FTIR, TGA, NH3-TPD and IR-pyridine. The performance of the Fe/HY catalysts was tested in gl...
