Au nanoparticle-functionalised WO3 nanoneedles and their application in high sensitivity gas sensor devices

Chem Commun (Camb). 2011 Jan 7;47(1):565-7. doi: 10.1039/c0cc02398a. Epub 2010 Nov 19.

Abstract

A new method of synthesising nanoparticle-functionalised nanostructured materials via Aerosol Assisted Chemical Vapour Deposition (AACVD) has been developed. Co-deposition of Au nanoparticles with WO(3) nanoneedles has been used to deposit a sensing layer directly onto gas sensor substrates providing devices with a six-fold increase in response to low concentrations of a test analyte (ethanol).
