Structural and sensing properties of a novel Fe/Fe2O3/polyoxocarbosilane core shell nanocomposite powder prepared by laser pyrolysis

Development of the IR laser pyrolysis for the synthesis of iron–doped TiO2 nanoparticles: Structural properties and photoactivity

“…Among various synthesis procedures, the IR laser pyrolysis technique [11] emerged recently as a powerful tool for the synthesis of technological important nanomaterials such as metal oxides and carbides [12], ceramics [13], metal-polymer nanocomposites [14], etc., with mean sizes ranging from a few nm to about 50 nm and with narrowly distributed diameters. The method is based on the resonance between the emission of a continuous wave (CW) CO 2 laser line and the infrared absorption band of a gas precursor and on subsequent heating of precursors by collisional energy transfer.…”

Direct Production of a Novel Iron‐Based Nanocomposite from the Laser Pyrolysis of Fe(CO)5/MMA Mixtures: Structural and Sensing Properties

“…A mixture containing iron pentacarbonyl (Fe(CO)5) and hexamethyldisiloxane (HMDSO)-as iron and polymer precursors, respectively, and ethylene-as reaction sensitizer was employed. Thick films prepared from the low-polymer content Fe-based/polymer material were examined for the sensing capabilities, by testing the variation of the electrical resistance in presence of CO, and CH 4 gases, at a working temperature of 450 • C [17].…”

Photochemistry Aspects of the Laser Pyrolysis Addressing the Preparation of Oxide Semiconductor Photocatalysts

“…A wide variety of gas-phase techniques has been developed for the fabrication of nanoparticulate structures [9] which could allow for homogeneous nucleation and may provide to some extent the control of particle size, particle shape, size distribution, particle composition, and degree of particle agglomeration. Among these synthesis procedures, the laser pyrolysis technique has been developed recently as a powerful tool for the synthesis of technological important nanomaterials such as metallic (Fe, Ti) oxides and composites [10][11][12][13], silicon crystals [14], nanocarbon [15], and ironsiloxane polymer nanoparticles [16].…”
