Sensors silica nanomaterials

This synthetic method was a simple and reproducible way to produce well-controlled composite metal- or metal-oxide-containing silica nanomaterials displaying interesting catalytic properties for gas-sensing applications. This study demonstrated that a single approach, deposition of a catalyst suspended in a liquid, may allow the sensitivity of gas sensors to be modulated it also showed that the nature of the material employed was critical for obtaining reproducible results. 

The growing of monodispersed RUO2 nanoparticles was achieved thanks to phosphonate groups contained within ordered mesoporous silicas. The use of mesoporous nanomaterials containing RUO2 nanoparticles (Ru02 Si02 nanomaterials) as catalytic filters for gas sensors, as well as after deposition as on-chip ... 

Over the last 2 decades, there has been an increasing interest in the development of one-dimensional nanomaterials, such as carbon nanotubes (Ounaies et al., 2003), bacterial nanofibers (Yano et al., 2005), silica nanotubes (Miyaji et al., 2003), and titanium dioxide nanotubes and nanowires (Yuan and Su, 2004). These new materials have relatively large specific surface areas and high aspect ratios hence, they are suitable for use as reinforcements, chemical probes, sensors, hydrogen storage, displays, and templates. One-dimension material/polymer nanocomposites allow us to take advantage of the extraordinary properties of one-dimension nanomaterials.
