TL;DR: Recent advantages in graphene preparation, sensor construction, and sensing properties of various graphene-based gas/vapor sensors, such as NH3, NO2, H2, CO, SO2,H2S, as well as vapor of volatile organic compounds are summarized.

TL;DR: In this article, a useful ammonia (NH3) gas sensor based on reduced graphene oxide (RGO) and polyaniline (PANI) hybrid was presented, where PANI nanoparticles were successfully anchored on the surface of RGO sheets by using RGO-MnO2 hybrids as both of the templates and oxidants for aniline monomer during the process of polymerization.

TL;DR: RGO, which was prepared via the reduction of graphene oxide by pyrrole, exhibited excellent responsive sensitivity and selectivity to ammonia (NH3) gas and showed great potential for ultrasensitive detection of NH3 gas in a wide variety of fields.

TL;DR: In this paper, a facile synthesis route of cuprous oxide (Cu2O) hollow spheres under different temperatures without the aid of a surfactant was introduced, and the obtained Cu2O hollow spheres were active photocatalyst for the degradation of methyl orange under visible light.

TL;DR: In this article, a gas sensor based on chemically reduced graphene oxide (CRG) by drop drying method was presented to create conductive networks between interdigitated electrode arrays, which is formed from the reduction of graphene oxide by p-phenylenediamine.
