“…The impact of reaction temperatures was also studied between 65 to 95 °C (Figure 7c) [45]. A significant yield increase was observed on raising the reaction temperature to 75 °C (followed by a more gradual rise at higher temperature) which may both reflect both enhanced rates of TAG hydrolysis and better miscibility of the methanol/WCO liquid phases, as previously reported [65,66]. The maximum 6 h FAME yield >95 % at the highest temperature.…”

“…Another study revealed the synthesis of the mixed metal oxide Mn@MgO-ZrO 2 via co-precipitation and impregnation method, and the utilization of the catalyst in the FAME production from kernel oil. 438 The efficiency of the catalyst in the FAME production was tested by changing the Mg/Zr ratio from 0.2 to 0.5, and it was found that 0.4 Mg/Zr has the optimal active sites, followed by impregnation of 4 wt% Mn to the MgO-ZrO 2 composite to enhance its reactivity and displayed 96.4% biodiesel yield. The high catalyst reactivity is due to a large number of active sites and the mesoporous nature of the catalyst.…”

“…Core-shell materials decorated with metallic systems play an important role in heterogeneous catalysis since the transfer of electrons demonstrates advantages in the stabilization of phases, preventing the migration and sinterization of the active sites and favoring higher activity of the final catalysts [5,35]. Recently, zirconia (ZrO 2 ) has received attention due to its amphoteric nature [36] and the ability to tune its chemical properties [37], electronic properties, thermal stability [38,39], and chemically inert inorganic oxide and redox properties [40]. Nonetheless, the deposition of one oxide on another oxide is interesting to understand.…”

The effect of the ZrO2 loading was studied on spherical SiO2@ZrO2-CaO structures synthetized by a simple route that combines the Stöber and sol-gel methods. The texture of these materials was determined using SBET by N2 adsorption, where the increment in SiO2 spheres’ surface areas was reached with the incorporation of ZrO2. Combined the characterization techniques of using different alcoholic dissolutions of zirconium (VI) butoxide 0.04 M, 0.06 M, and 0.08 M, we obtained SiO2@ZrO2 materials with 5.7, 20.2, and 25.2 wt % of Zr. Transmission electron microscopy (TEM) analysis also uncovered the shape and reproducibility of the SiO2 spheres. The presence of Zr and Ca in the core–shell was also determined by TEM. X-ray diffraction (XRD) profiles showed that the c-ZrO2 phase changed in to m-ZrO2 by incorporating calcium, which was confirmed by Raman spectroscopy. The purity of the SiO2 spheres, as well as the presence of Zr and Ca in the core–shell, was assessed by the Fourier transform infrared (FTIR) method. CO2 temperature programmed desorption (TPD-CO2) measurements confirmed the increment in the amount of the basic sites and strength of these basic sites due to calcium incorporation. The catalyst reuse in FAME production from canola oil transesterification allowed confirmation that these calcium core@shell catalysts turn out to be actives and stables for this reaction.
