Title: | H-2 sensors based on WO3 thin films activated by platinum nanoparticles synthesized by electroless process | Authors: | Zhang, Chao Kanta, Abdoul-Fatah YIN, Hong Boudiba, Abdelhamid D'HAEN, Jan Olivier, Marie-Georges Debliquy, Marc |
Issue Date: | 2013 | Publisher: | PERGAMON-ELSEVIER SCIENCE LTD | Source: | INTERNATIONAL JOURNAL OF HYDROGEN ENERGY, 38 (6), p. 2929-2935 | Abstract: | Platinum (Pt) nanoparticles were successfully synthesized on tungsten oxide (WO3) thin films by electroless process without any further post-treatment. The prepared Pt nanoparticles were characterized by X-ray diffraction, X-ray photoelectron spectroscopy and field-emission scanning electron microscopy. Gas sensors based on the Pt-WO3 films were found to provide repeatable and significant responses to ppm-level H-2. The size of Pt nanoparticles increases with the deposition time and has improved the sensing characteristics of the sensors. The work in this paper paves a facile way to the fabrication of Pt nanoparticles on metal oxide surface at a low temperature (68 degrees C). Copyright (C) 2012, Hydrogen Energy Publications, LLC.
