NO 2 is an oxidizing gas, which is considered to be the most dangerous and most toxic gas
that should be controlled. Because of the advantages of high sensitivity, selectivity, stability …

The release of toxic and harmful gases seriously endangers human health and social and
environmental safety. Sensitive determination of these gases is urgently needed to meet the …

Abstract Three-dimensional (3D) hierarchical Cu 2 O-CuO microflowers assembled by
nanorods were successfully obtained through an environmentally friendly hydrothermal …

Many recent efforts are directed toward developing high-performance gas sensors based on
metal oxide nanostructures operating at room temperature, as it lowers the power …

Gas sensors play a pivotal role in the Internet of Things-based environmental monitoring
systems, where sensing materials are core determinants of gas sensing performance …

Air pollution is nowadays a big issue regarding the health of human beings. Among the toxic
gases emitted in the atmosphere, NO 2 is the most problematic one and a lot of countries or …

In this paper, we report a size-controlled metal oxide under a low-temperature process for
the fabrication of an electrochemical sensor based on ultra-small nickel oxide (NiO) …

Abstract In this work, 2D/2D ZnO/gC 3 N 4 heterojunction composite was synthesized
through an ultrasonic mixing and subsequent calcination process. The gas-sensing …

In this paper, a coral-like tin diselenide/MOFs-derived flower-like tin dioxide (SnSe 2/SnO 2)
nanocomposite film sensor was fabricated by hydrothermal method for NO 2 gas detection …

This paper introduces a coral-like Au-modified SnSe 2 nanocomposite prepared by a simple
hydrothermal method. The pure-and Au-modified SnSe 2 film sensors were prepared on the …
