Since the first suggestion, during the 1950s, that high-surface-area metal oxides could be
used as conductometric gas sensors enormous efforts have been made to enhance both the …

The mechanistic description of gas sensing on inorganic, organic, and polymeric materials is
of great scientific and technological interest. The understanding of surface and bulk …

The paper critically reviews the state of the art in the field of experimental techniques
possible to be applied to the study of conductometric gas sensors based on semiconducting …

Tin dioxide is the most commonly used material in commercial gas sensors based on
semiconducting metal oxides. Despite intensive efforts, the mechanism responsible for gas …

Semiconducting metal oxides are widely used for gas sensors. The resulting chemiresistor
devices, however, suffer from non-linear responses, signal fluctuations and gas cross …

Raman surface vibration modes have been measured for SnO2 nanocrystalline powders
with grain sizes of 3− 36 nm and a specific surface area up to 180 m2 g-1, which were …

The role and activity of catalytic additives on solid-state gas sensors are determined by the
additive chemical state, aggregation form and interaction with the semiconductor oxide. All …

A study on reactivity of p+ porous silicon layers (PSL) to different gas atmosphere has been
carried out. Substrate doping was 5–15 mΩ cm and 0.5 Ω cm, porosity ranged from 30 to …

Diffuse reflectance infrared Fourier transform measurements were performed on tin oxide
based thick film gas sensors operated in normal working conditions. We characterised SnO2 …

The development of gas sensors that are based on metal/metal‐oxide nanoclusters has
attracted intensive research interest in the last years. Nanoclusters are suitable candidates …
