Gas sensors are fundamental for continuous online monitoring of volatile organic compounds. Gas sensors based on semiconductor materials have demonstrated to be highly competitive, but are generally made of expensive materials and operate at high temperatures, which are drawbacks of these technologies. Herein is described a novel ethanol sensor for room temperature (25 °C) measurements based on hematite (α‑Fe2O3)/silver nanoparticles. The AgNPs were shown to increase the oxide semiconductor charge carrier density, but especially to enhance the ethanol adsorption rate boosting the selectivity and sensitivity, thus allowing quantification of ethanol vapor in 2–35 mg L−1 range with an excellent linear relationship. In addition, the α-Fe2O3/Ag 3.0 wt% nanocomposite is cheap, and easy to make and process, imparting high perspectives for real applications in breath analyzers and/or sensors in food and beverage industries. This work contributes to the advance of gas sensing at ambient temperature as a competitive alternative for quantification of conventional volatile organic compounds.

To determine thin films’ properties of commercially available gallic acid molecule, they were deposited onto a suitable substrate using spin coater. UV–Visible absorption spectroscopy and atomic force microscopy (AFM) were employed for the characterization of the deposited thin films. Characterization results obtained by these two techniques indicated that the gallic acid molecules are suitable for transfer onto a glass or quartz substrate. Gas-sensing properties and thickness of these thin films were elucidated using surface plasmon resonance (SPR). Thickness values of spun thin films were obtained at different spinning speeds. Then, the gas-sensing properties were examined by exposing them to the vapors of four volatile organic compounds (VOCs). It was found that the spun films of this material were selective for methanol vapor yielding rapid response and recovery time and thin films of gallic acid exhibited reversible changes in the optical behavior, which makes them suitable for practical methanol-detection applications.
