TL;DR: The gas sensing properties of metal oxide nanostructures assembled by nanoparticles are reviewed in this article and the effect of doping is summarized and the perspectives ofMetal oxide gas sensor are given.

TL;DR: Au/SnO2/reduced graphene oxide (RGO) nanocomposites have been successfully synthesized by a one-step method as discussed by the authors, which revealed that Au nanoparticles obviously enhanced the sensitivity by comparing with the pure SnO 2/RGO nanocomposition.

TL;DR: Porous flower-like CuO/ZnO nanostructures were obtained using a facile chemical solution method combined with subsequent calcination in this paper, which resulted from the thermal decomposition of the as-prepared precursors, i.e., flowerlike zinc copper hydroxide carbonate, and were characterized through X-ray diffraction, field emission scanning electron microscopy, thermogravimetric-differential thermal analysis, and Brunauer-Emmett-Teller N2 analyses, among others.

TL;DR: In this article, a template-free, economical aqueous solution method combined with subsequent calcination was used to synthesize uniform and monodisperse porous ZnSnO3 cubes.

TL;DR: The results show that Au-modified HPSCZNs-based sensors exhibit a high response to TMA; the linear range is from 10 to 300 ppb; while the detection limit is 10 ppb, which is the lowest value to the authors' knowledge.
