Innovative solvo-combustion route for the rapid synthesis of MoO3 and Sm2O3 materials
Source abstract
Abstract
Abstract This paper reports the development of a solvo-combustion synthesis route using acetylacetone as the novel fuel and ethanol as the solvent, with water excluded from the system. MoO 3 and Sm 2 O 3 materials synthesized by this route were characterized by various physicochemical techniques. X-ray diffraction (XRD) analysis revealed that the as-prepared materials contained α-MoO 3 and cubic Sm 2 O 3 began to crystallize at 500 °C. Scanning electron microscopy (SEM) analysis indicated that MoO 3 particles possessed a plate shape, whereas Sm 2 O 3 particles formed foam-like agglomerates. The Sm 2 O 3 materials exhibited surface areas at least 2 times greater than those of the MoO 3 materials. The nature of each oxide and the reagents used in the synthesis played important roles in determining the resulting morphology and surface area. This solvo-combustion route is expected to be suitable for the synthesis of complex oxides with attractive specific surface areas.
