Abstract Pristine and Ag-added (1.5, 3.5 and 5.5 wt%) ZnO nanoparticles (NPs) were
synthesized by a Pechini sol-gel route for evaluation of their gas sensing properties. The …

Bilayer SnO 2–WO 3 nanofilm sensors with high sensitivity and selectivity for NH 3 gas were
developed. The sensitized WO 3 nanofilms (5–15 nm) were deposited on the top of SnO 2 …

The size and dispersity of nanoparticles (NPs) determine the properties that such particles
display. In this study, synthesis of silver nanoparticles in a coaxial flow reactor (CFR) was …

Abstract The Au-decorated SnO 2 nanoflowers (NFs) composites were synthesized via a
facile impregnation route by using chloroauric acid and SnO 2 powder as precursors without …

The effect of Ag and Au additives on the optimum operating temperature and response level
of thick film SnO 2 gas sensors is investigated and compared with the results of pure SnO 2 …

The detection of the toxic H 2 S gas is of great practical, environmental and industrial
interest. This work presents sensing devices fabricated with Ag-doped CaCu 3 Ti 4 O 12 …

Metal oxide semiconductors stand at an essential frontier of chemiresistive substance for
gas sensor assembly to detect the volatile organic compounds, especially in case of the …

In view of the low sensitivity, high operating temperature and poor selectivity of acetone
measurements, in this paper much effort has been paid to improve the performance of …
