Efficient biodiesel production from Jatropha curcus using CaSO4/Fe2O3-SiO2 core-shell magnetic nanoparticles

Core shell nanostructures have endorsed great enhancements in the production of biodiesel with well-controlled size, shape, and surface properties. A simple and reproducible hierarchically porous core-shell CaSO4/Fe2O3-SiO2 material with controllable core morphology was developed. The materials with a well mesoporous structure were prepared by ethanol/H2O media using NaNO3 as the etchant to construct the co-valent bond in Fe2O3 framework, and the CH3COONa was an electrostatic supporter and subordinate reducing agent under mild. Solvothermal conditions. The morphology, porosity and conjugated structure of CaSO4/Fe2O3-SiO2 were measured systematically. The materials of CaSO4/Fe2O3-SiO2 showed remarkable performance in biodiesel production with crude Jatropha curcus and methanol. At suitable state, the biodiesel production reached 94%. Furthermore, the material was easily dispersed in the reaction system, quickly…
