Volatile organic compounds (VOCs), which originate from painting, oil refining and vehicle
exhaust emissions, are hazardous gases that have significant effects on air quality and …

Since the first suggestion, during the 1950s, that high-surface-area metal oxides could be
used as conductometric gas sensors enormous efforts have been made to enhance both the …

Butanone is a precursor chemical and detrimental to human body, as a consequence, it is
significant for social stability to accurately detect trace butanone. In this paper, Co 3 O 4/SnO …

Abstract Undoped and 0.2-1.0 mol% Rh-doped SnO 2 nanofibers were fabricated using
electrospinning combined with calcination treatment. The fibrous morphology of these …

Herein, we report the synthesis, characterization, and gas sensing applications of Pt
nanoparticles-decorated SnO 2 nanoneedles synthesized through a facile hydrothermal …

Humidity dependence of gas sensors is one of the main obstacles for practical application.
Through Ru doping into NiO flower-like microspheres, which are synthesized by a one-step …

Pt-doped flower-like SnO 2 nanocomposites were successfully synthesized by hydrothermal
process, followed by a simple thermal reduction method. And, their morphology, composition …

Noble metals or oxide catalysts have traditionally been loaded or doped to enhance the gas
sensing properties of oxide semiconductor chemiresistors. However, the selective detection …

Gas sensors based on SnO 2 nanostructures have been extensively investigated in recent
years. Many recent investigations have focused on synthesizing 0D, 1D, 2D and 3D SnO 2 …

Highly sensitive sensors to detect small amounts of gases are expected to be used for
monitoring air quality and analyzing breath for medical diagnosis. We report a highly …
