Solvent-free synthesis and characterization of bimetallic UiO-66(Zr/Sn) heterogeneous catalyst for biodiesel production

Article scientifique 2022 Anglais

Résumé

Abstract UiO-66(Zr) has been demonstrated to be an efficient heterogeneous catalyst in the esterification of oleic acid and methanol for biodiesel production. For the development of multi-functional sites in the structure of UiO-66(Zr), direct synthesis of UiO-66(Zr) with extra metal centers is a challenge. Based on our previous work of solvent-free synthesis, tin-doped UiO-66(Zr) was prepared under solvent-free conditions. The produced materials were analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD), N2 sorption technique, Fourier transform infrared (FT-IR) spectroscopy, X-ray photoelectron spectroscopy (XPS) and temperature-programmed desorption (TPD) analysis of NH3. The results indicate that UiO-66(Zr/Sn)-green with bimetal centers exhibits superior catalytic performance in the esterification of oleic acid. Additionally, the influence of tin integration on the structure and reactivity of UiO-66(Zr) significantly accelerates the esterification process at room temperature. Such catalyst could easily be recycled and reused.
