Gas Sensors Based on Titanium Oxides (Review)

Nanostructured titanium compounds have recently been applied in the design of gas sensors. Among compounds, oxides (TiO2) are most frequently used sensing devices. Therefore, this review, we paying significant attention to variety allotropic modifications oxides, which include anatase, rutile, brukite. Very recently, applicability non-stoichiometric oxide (TiO2−x)-based layers for sensors was demonstrated. For reason, addressing some research related formation (TiO2−x) and Magnéli phase (TinO2n−1)-based suitable sensor design. The promising hetero- nano-structures based on these discussed. It is also outlined that during past decade, many new strategies synthesis TiO2 conducting polymer-based composite materials were developed, found specific application areas. highlighting how methods, can be polymer composites, tune characteristics leading towards advanced applications technological fields. possibility sensitivity selectivity compound-based addressed. In other recent reviews development overviewed. Some designs titanium-based nanomaterials outlined.
