The direct synthesis of glycerol carbonate via glycerol carbonylation by CO2 suffers from thermodn. limitation. In this study, light was introduced into the thermal-driven reaction system to synergistically break the equilibrium of the reaction. A series of xLa2O2CO3-ZnO catalysts were prepared using a hydrothermal method and used for the photo-thermal transformation of glycerol and CO2 into glycerol carbonate. Inductively coupled plasma-at. emission spectrometry (ICP-AES), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), CO2 temperature-programmed desorption (CO2-TPD), XPS, UV-visible (UV-vis) spectroscopy, photoluminescence (PL) spectroscopy and Fourier transform IR (FT-IR) spectrometry were employed to characterize the crystalline structure, the number of basic sites, textural properties and optical properties of the catalysts. The photo-thermal synergism as well as the cooperation between ZnO and La2O2CO3 contributed to its catalytic performance, thus achieving a glycerol conversion of 6.9% under the reaction conditions of 150°C, 5.5 MPa CO2, and 20 mmolGL gCat-1 with a reaction time of 6 h when 20% La2O2CO3-ZnO was used as the catalyst.
