24. Change in the Electrical Conductivity of Graphene Oxide Film after Treatment with Supercritical Fluids (iso-С3Н7ОН, Н2О).

Abstract

A graphene oxide film fabricated by removing water from a graphene oxide dispersion is a characteristic dielectric. The graphene oxide layers in such a film are interconnected through van der Waals interactions of oxygen-containing functionalities and cluster interlayer water. It has been shown that, after treatment of the film with supercritical fluids based on water and isopropyl alcohol, its robust structure is not destroyed, but the surface is "graphenized" and it acquires new properties. The resulting materials were studied by physicochemical methods of analysis (C, H, N analysis, XRD, IR and Raman spectroscopy). An electrophysical study of the film treated with supercritical isopropanol has demonstrated that the temperature dependence corresponds to a narrow-gap semiconductor, and the resistivity determined by the four-probe method at room temperature was ~3 Ω m/mm2.

32. Reactions of MnO2, Mn2O3, α-Bi2O3, and Bi12Ti1 – xMn xO20with Supercritical Isopropanol.

Author

Buslaeva, E., Kravchuk, K., Kargin, Yu., and Gubin, S.

Abstract

Heterogeneous reactions between supercritical isopropanol and metal oxides were studied for the first time. The results demonstrate that Bi2O3 is reduced by isopropanol to metallic bismuth, while MnO2 and Mn2O3 are reduced to Mn3O4 (hausmannite). The possibility of oxygen extraction from nonstoichiometric oxides is demonstrated by the example of the reaction Bi12Ti1 – xMn5+ xO20 + δ → Bi12Ti1– xMn2+ xO20 – δ . [ABSTRACT FROM AUTHOR]
