One-step hydrothermal coating approach to photocatalytically active oxide composites


Zhou, Y; Krumeich, F; Heel, A; Patzke, Greta R (2010). One-step hydrothermal coating approach to photocatalytically active oxide composites. Dalton Transactions, 39(26):6043-6048.

Abstract

Three-dimensional Bi2WO6/TiO2 hierarchical heterostructures with secondary anatase TiO2 nanoparticles grown on primary Bi2WO6 microspheres have been successfully obtained by a low temperature hydrothermal method. The hierarchical Bi2WO6/TiO2 structures displayed significantly enhanced visible-light-driven photocatalytic activity in comparison to isolated Bi2WO6 microspheres and TiO2 nanoparticles. Furthermore, this methodology is of general interest, because it can be used to fabricate other oxide heterostructures, such as BiVO4/TiO2 and Bi2MoO6/TiO2.

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.
