Surface chemistry, energy conversion, and related applications.

Abstract

Oxide nanomaterials have an impact in many interdisciplinary fields of the emerging nanotechnologies as reported here. They are components of heterogeneous catalyst systems with specific features that are outlined. In photocatalysis, chemical reactions are catalytically enabled by photon-energy conversion: oxide photocatalysts are prominent and discussed in relation to the photochemical water splitting reaction. Solid oxide fuel cells are promising energy sources, in which oxide nanomaterials are expected to boost further progress. Solar energy materials are elements of the “green chemistry” revolution for energy saving: the chromogenic functionality of oxide nanolayers with use in advanced fenestration is introduced. The formation and structure of corrosion protective nanolayer oxides, which is vital for the everyday use of metallic components, are examined. Biotechnology applications of oxide nanostructures comprise their biocompatibility, antibacterial properties, theranostic systems as well as biosensor platforms. An interesting bioapplication of ferroelectric oxide thin films is reported.
