Journal ArticleDOI
Radio-frequency plasma functionalization of carbon nanotubes surface O2, NH3, and CF4 treatments
Alexandre Felten,Carla Bittencourt,Jean-Jacques Pireaux,G. Van Lier,Jean-Christophe Charlier +4 more
TL;DR: In this paper, the influence of various plasma conditions (power, type of gas, treatment time, pressure, position of the CNT sample inside the chamber) on the functionalization of the MWCNT surface was analyzed by x-ray photoelectron spectroscopy.
Journal ArticleDOI
Au nanoparticle-functionalised WO3 nanoneedles and their application in high sensitivity gas sensor devices
Stella Vallejos,Toni Stoycheva,Polona Umek,Cristina Navío,Rony Snyders,Carla Bittencourt,Eduard Llobet,Christopher S. Blackman,Savio J. A. Moniz,Xavier Correig +9 more
TL;DR: 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).
Journal ArticleDOI
Oxygen functionalisation of MWNT and their use as gas sensitive thick-film layers
Radu Ionescu,E.H. Espinosa,E. Sotter,Eduard Llobet,Xavier Vilanova,Xavier Correig,Alexandre Felten,Carla Bittencourt,G. Van Lier,Jean-Christophe Charlier,J.J. Pireaux +10 more
TL;DR: In this paper, multi-wall carbon nanotubes (MWNT) were functionalised in an oxygen-based atmosphere by an inductively coupled RF-plasma at 13.56 MHz.
Journal ArticleDOI
Aerosol-Assisted CVD-Grown WO3 Nanoneedles Decorated with Copper Oxide Nanoparticles for the Selective and Humidity-Resilient Detection of H2S
Fatima Ezahra Annanouch,Z. Haddi,Stella Vallejos,Polona Umek,Peter Guttmann,Carla Bittencourt,Eduard Llobet +6 more
TL;DR: A gas-sensitive hybrid material consisting of Cu2O nanoparticle-decorated WO3 nanoneedles is successfully grown for the first time in a single step via aerosol-assisted chemical vapor deposition and has excellent sensitivity and selectivity to hydrogen sulfide and a low detection limit.
Journal ArticleDOI
Single‐Step Deposition of Au‐ and Pt‐Nanoparticle‐Functionalized Tungsten Oxide Nanoneedles Synthesized Via Aerosol‐Assisted CVD, and Used for Fabrication of Selective Gas Microsensor Arrays
Stella Vallejos,Polona Umek,Toni Stoycheva,Fatima Ezahra Annanouch,Eduard Llobet,Xavier Correig,Patrizia De Marco,Carla Bittencourt,Christopher S. Blackman +8 more
TL;DR: In this article, a single-step method via aerosol-assisted chemical vapour deposition, onto microelectromechanical system (MEMS)-based gas-sensor platforms is demonstrated to be an effective route to incorporate metal nanoparticles (NP) or combinations of metal NPs into nanostructured materials, resulting in an attractive way of tuning functionality in metal oxides (MOX).
