TL;DR: A gas-sensitive hybrid material consisting of Cu2O nanoparticle-decorated WO3 nanoneedles is successfully grown for the first time in a single step via aerosol-assisted chemical vapor deposition and has excellent sensitivity and selectivity to hydrogen sulfide and a low detection limit.

TL;DR: In this article, a single-step method via aerosol-assisted chemical vapour deposition, onto microelectromechanical system (MEMS)-based gas-sensor platforms is demonstrated to be an effective route to incorporate metal nanoparticles (NP) or combinations of metal NPs into nanostructured materials, resulting in an attractive way of tuning functionality in metal oxides (MOX).

TL;DR: Gas-sensing results revealed that decoration with PdO NPs led to an ultrasensitive and selective hydrogen (H2) gas sensor (sensor response peaks at 1670 at 500 ppm of H2) with low operating temperature (150 °C), and humidity measurements showed that Pd O/WO3 sensors displayed low-cross-sensitivity toward water vapor, compared to bare WO3 Sensor.

TL;DR: In this article, the authors analyzed low-frequency resistance fluctuations in commercial Taguchi gas sensors and the recently developed tungsten trioxide (WO3) gas-sensing layers, exhibiting a photo catalytic effect.

TL;DR: New Approaches for Improving Selectivity and Sensitivity of Resistive Gas Sensors: A Review as discussed by the authors is a review of new approaches for improving selectivity and sensitivity of resistive gas sensors.
