Gas sensors based on metal oxides semiconductor (MOS) have attracted extensive attention
from both academic and industry. ZnO, as a typical MOS, exhibits potential applications in …

In this work, LaCoO 3 (LCO) nanoparticles were synthesized by sol-gel method and
modified on the surface of ZnO. The LaCoO 3-modified ZnO (LCO/ZnO) nanometer flake …

The exponential population growth on earth has put an enormous strain on energy
resources, which come in various forms like fossil fuels, geothermal energy, and so on …

Fast response recovery time and high response value are very necessary indicators for H 2
S sensors in the past few years. As H 2 S is a toxic gas that has great threat to human life …

Abstract Hydrogen sulfide (H 2 S), as a representative food spoilage gas produced by the
breakdown of sulfur-containing proteins, is highly irritant and toxic. Designing gas sensors …

ZnO/CuO nanocomposites were derived from a metal-organic framework (MOF) using a
simple precipitation method. The mesoporous nature, crystallinity, and fine particle size of …
