This review (with 200 references) summarises the state of the art of gas and vapour sensors
based on the use of vanadium oxide (VO x; with V occurring in various valencies) …

NiWO4 microflowers with a large surface area up to 79.77 m2· g–1 are synthesized in situ
via a facile coprecipitation method. The NiWO4 microflowers are further decorated with multi …

Polyaniline (PANI) functionalized multiwall carbon nanotubes (MWCNTs) were prepared via
in situ chemical polymerization process of aniline, in which MWCNTs were spray coated on …

Multiplexed gas detection at room temperature is critical for practical applications, such as
for tracking the complex chemical environments associated with food decomposition and …

A high-sensitivity ammonia gas sensor based on molybdenum disulfide/zinc oxide (MoS
2/ZnO) nanocomposite film was reported in this paper. The multilayered film of MoS 2/ZnO …

Abstract Two-dimensional (2D) materials have attracted significant attention for device
applications due to their unique structural, electronic and catalytic properties. Here, we have …

Triethylamine (TEA), as a common and widely used industrial raw material, is extremely
hazardous to the environment and human health. Therefore, the development of a portable …

The exhaust monitoring for in-situ quantification of gas pollutants has always been a
challenge due to the harsh thermo-chemical environments, for which the solid-electrolyte …

Nitrogen oxides (NO X) are often produced in industrial combustion processes and are
among the most harmful air contaminants. Selective catalytic reduction (SCR) is currently the …

We have developed a fast and highly sensitive gas sensor based on the Pd/V 2 O 5 thin
films for the low temperature detection of hydrogen in the range 2–500 ppm in air. Sensor …
