Theory of gas sensors: response of an electrochemical sensor to multi-component gas mixtures

Sensors and Actuators B: Chemical, 1996
A first-principles model of the operation of an electrochemical metal oxide gas sensor had been previously used to analyze the response when the sensor was exposed to a simple gas mixture (e.g. O 2 /CO/CO 2 ). Here, the model is extended to study the sensor response to a complex gas mixture containing two reducing gases e.g.

Black Phosphorus Gas Sensors

ACS Nano, 2015
The utilization of black phosphorus and its monolayer (phosphorene) and few-layers in field-effect transistors has attracted a lot of attention to this elemental two-dimensional material. Various studies on optimization of black phosphorus field-effect transistors, PN junctions, photodetectors, and other applications have been demonstrated.

Mesoporous materials as gas sensors

Chem. Soc. Rev., 2013
Ordered mesoporous materials have great potential in the field of gas sensing. Today various template-assisted synthesis methods facilitate the preparation of silica (SiO2) as well as numerous metal oxides with well-defined, uniform and regular pore systems.
