Abstract

The promising structural features of the defect spinel-type oxide γ-Ga2O3 and its application potential as a host for new nanoscale solid solutions have been far less explored than its analog γ-alumina, which is widely used in catalysis. Therefore, new synthetic approaches are required to access transition metal-doped γ-Ga2O3 materials on the nanoscale. We have established the first microwave–hydrothermal route for the challenging incorporation of Cu2+ ions into a nanostructured γ-Ga2O3 matrix. Homogeneous γ-Ga2O3:Cu2+ materials with high surface areas are formed within less than 30 min, and the copper content can be adjusted through the synthetic parameters. The copper distribution within the spinel matrix was analyzed with a wide range of compositional, structural, spectroscopic and magnetic characterizations.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
