The observation of reductive decomposition with SEC-current-time-temperature curves on the binary line V2O5-Nb2O5 is a useful method to determine qualitatively and quantitatively (“quasi in situ”) the known ternary coexistence regions. By reduction of VO2 the Magneli-Phases VnO2n-1 are generated. The method is generally applicable and allows rapid information by reductive decompositon or oxidative formation in coexistence regions.The conditions of decomposition can be optimized for a given system. Slow solid-gas equilibria are not detectable by this method.

AbstractObjective: Cyclodextrins have been used to catalyze chemical reactions in the synthesis of different materials. The aim of this study is to produce nanoparticles using cyclodextrin as a nanoreactor.Methods: In this study, nanoparticles from the solid phase of iron oxide (FeResults: The images demonstrated that the nanoparticles exhibited a polyhedric shape with a diameter of 100 nm for FeConclusion: Based on this characterization, the proposed technique proved to be an efficient, low-cost, convenient method for the production of sub-micrometric and nanometric solid phases and can likely be scaled up for industrial use. The results demonstrate the possibility of producing nanoparticles using cyclodextrin as a nanoreactor.
