Abstract EN
Iron/iron oxide-based nanocomposites were prepared by IR laser sensitized pyrolysis of Fe(CO)5 and methyl methacrylate (MMA) mixtures.
The morphology of nanopowder analyzed by TEM indicated that mainly core-shell structures were obtained.
X-ray diffraction techniques evidence the cores as formed mainly by iron/iron oxide crystalline phases.
A partially degraded (carbonized) polymeric matrix is suggested for the coverage of the metallic particles.
The nanocomposite structure at the variation of the laser density and of the MMA flow was studied.
The new materials prepared as thick films were tested for their potential for acting as gas sensors.
The temporal variation of the electrical resistance in presence of NO2, CO, and CO2, in dry and humid air was recorded.
Preliminary results show that the samples obtained at higher laser power density exhibit rather high sensitivity towards NO2 detection and NO2 selectivity relatively to CO and CO2.
An optimum working temperature of 200°C was found.
