Alkoxide Route to Re- and Mo-Based Metallic and Oxide Materials
摘要:
The oxomethoxo complexes Re4O2(OMe)(16), Re4O6(OMe)(12), and Re4-xMoxO6(OMe)(12) (x = 0.10, 2.82) are prepared via anodic dissolution of rhenium and molybdenum in methanol in the presence of LiCl. The phase composition of the solid products obtained by decomposing the synthesized complexes in oxidizing inert, and reducing atmospheres is examined by x-ray diffraction. The results demonstrate that, by decomposing these complexes in the range 150-500degreesC, one can obtain Re-based metallic and oxide materials: ReO3, monoclinic ReO2, orthorhombic (Re,Mo)O-2 solid solutions, metallic Re powder, and Re-Mo alloys, including nanocrystalline powders.
