Available in PDF, EPUB and Kindle. Book excerpt: Hydrothermal method has proven to be an excellent method for the synthesis of novel metal oxides and vanadates. This research pertains to the synthesis of novel lead chlorovanadate compound and of a known alkali metal trivanadate compound, KV3O8 by hydrothermal method This method has been used to synthesize many inorganic oxide compounds Hydrothermal synthesis is the use of aqueous solvents under high temperature and high pressure to dissolve and recrystallize materials. Compounds with interesting structure and physical properties are often obtained from this technique that is known as one of the low-temperature synthesis techniques for solid state compounds. There are many studies that have been done on oxides in the Pb-V-O systems There are also many vanadium oxides containing Pb, V, O elements in Pb-V-O system such as Pb1.32V8.35O16.7, PbV6O11, PbV2O6, Pb2V3O8.5, and .-PbxV2O5 bronzes (x = 0.3). In an attempt to synthesize vanadium oxides at low temperature, we were able to obtain needle shaped yellow crystals of PbVO3Cl. In the nature, there is a kombatite mineral, Pb14(VO4)2O9Cl4, with the same composition of elements. A new lead chlorovanadate, PbVO3Cl, was obtained from the reaction of NaVO3 and PbCl2 in aqueous solution of B(OH)3. The compound was prepared in an autoclave that was filled with aqueous solution of B(OH)3 and heated at 170oC for 3 days. The compound crystallizes in the space group Pnma of the orthorhombic system with formula units in a cell of dimensions a = 10.022(2)

Abstract: Solid basic metal oxides have been extensively studied for biodiesel production via transesterification, researches are now focused on attaining high catalytic activity and durability towards one-step alkali transesterification, as well as high stability towards high free fatty acids (FFAs) and water content in oils for simultaneous esterification and transesterification, to enable their commercialization in industry. This work encompasses the design and characterization of three mixed metal oxide systems, with a detailed evaluation of their potential application in catalyzing transesterification of camelina oil to yield biodiesel. Na0.1Ca0.9TiO3 nanorods were synthesized via a simple alkaline hydrothermal pathway with ethanol as a co-solvent. Owing to their high basic strength of 11A new class of mesoporous Zn/MgO catalyst was synthesized by a simple alkaline hydrothermal method. Zn/MgO calcinated at 600 ℃ exhibited 88.7% biodiesel conversion at 120 ℃ with 3% w/w catalyst, 24:1 methanol to oil molar ratio for 8 h. The catalyst could be reused for five runs without significant loss of activity (>=84.0% biodiesel conversion). The excellent catalyst performance is possibly attributed to its high surface area and large mesopores. The higher surface basic sites density as compared to mesoporous MgO, as indicated by higher total basicity determined from benzoic titration and an increased lattice O2- percentage as revealed from XPS, attributing to its superior catalytic activity. A series of nano-sized MgO-ZnO catalysts with precise stoichiometry were successfully prepared by a simple EDTA complexing approach. Mg0.5Zn0.5 calcinated at 600 ℃ gave a maximum biodiesel conversion of 89.3% at 120 ℃ with 3% w/w catalyst, 24:1 methanol to oil molar ratio for 8 h. Its superior catalytic performance to MgO is mainly associated with the high basic sites density as determined from benzoic titration and XPS. The biodiesel conversion retained over 83.0% for five runs. The enhanced catalyst activity and stability might be contributed by the incorporation of Zn2+ for Mg2+ in MgO lattice and a high homogeneous distribution of MgO particles on ZnO, with the formation of Mg-O-Zn bond as evidenced by Fourier transform infrared spectroscope (FTIR) and XPS. The catalyst also demonstrated high tolerance to FFAs (10% w/w) and water (2% w/w) content, which make it desirable for direct conversion of oils with high FFAs level to biodiesel in a single-step process. Lastly, a Zn/La2O3 catalyst was synthesized by a simple hydrothermal pathway. It exhibits a higher basic strength than La2O3, as evidenced by the slightly lower O1s binding energy determined by XPS, leading to a higher catalytic activity. The enhanced catalytic activity and stability is likely contributed by the incorporation of Zn2+ for La3+ in the lattice. Using 1% w/w Zn/La2O3 as catalyst, the highest biodiesel conversion of 92.7% was obtained at 120 ℃ for 16 h with 36:1 methanol to oil molar ratio. The effective catalyst displayed a biodiesel conversion greater than 84.0% for four runs. DOI: 10.5353/th_b5204899 Subjects:
