Bi2O3 or Bi6S2O15 nanowires? The role of templating inorganic additives in nanomaterials formation

Abstract

The role of templating sulfate anions in the hydrothermal formation of nanowires from Bi2O3 and K2SO4 is critically discussed on the basis of X-ray diffraction patterns, electron microscopy studies and ion exchange experiments. Thorough analytical investigations of the obtained nanowires together with mechanistic information from in situ studies indicate that sulfate ions are structurally incorporated into the product, thereby transforming the bismuth oxide precursors into a new material. We present an in-depth analysis of structural data in order to point out potential pitfalls of inorganic additives as templates in solution.

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.
