Monitoring and detecting carbon monoxide (CO) are critical because this gas is toxic and
harmful to the ecosystem. In this respect, designing high-performance gas sensors for CO …

For the sake of people's health and the safety of the environment, more efforts should be
directed towards the fabrication of gas sensors that can operate effectively at room …

In this work, Fe-doped ZnO (Fe–ZnO) porous nanosheets gas sensors were fabricated to
detect acetone gas. The pure and 0.5, 1, 3 mol% Fe–ZnO nanosheets were synthesized …

Abstract Pure ZnO and Nd 2 O 3-doped ZnO nanoparticles were synthesized by a
hydrothermal method. The crystal microstructure morphology and the surface physico …

The properties of H2S gas sensing were investigated using a ZnO nanostructure prepared
with AZO (zinc oxide with aluminium) and Al surfaces which were developed on a MEMS …

Nitrogen dioxide (NO 2) exposure can have several adverse health impacts on people,
especially the respiratory system. Low selectivity, a lack of long-term stability, and structural …

In this study, undoped and transition-metal (Ni/Cu) doped ZnO nanostructure was
synthesized for its ability to discriminate NO 2 test gas using simple sol–gel spin coating …

In the present work, CO gas sensor based on ZnO (non-annealed) and ZnO: Cu (post-
annealed) were prepared using chemical bath deposition technique using Zinc Nitrate …

In this study, Ag2O/In2O3 composites with hollow fish basket-like structure were one-step
facile synthesized by modifying In2O3 by means of Ag2O doping using hydrothermal …
