Clean air is probably the most essential before water for human health and well-being, but
human activities associated with socioeconomic developments are the key pollution …

Hazardous gases have been strongly associated with being a detriment to human life within
the environment. The development of a reliable gas sensor with high response and …

Abstract Tungsten oxide (WO 3), a typical n-type gas-sensing material, has attracted
considerable attention to detect various hazardous gases. Previous studies indicated that …

In this work, hierarchical flower-like Ni-doped Co 3 O 4 was synthesized via a facile one-step
coprecipitation method. In the synthesis process, a series of solvent-dependent experiments …

In this study, a straightforward coassembly strategy is demonstrated to synthesize Pt
sensitized mesoporous WO3 with crystalline framework through the simultaneous …

Abstract Pure ZnO nanoparticles (NPs), ZnO/CuO and Al-ZnO/CuO nanocomposites (NCs)
were prepared using co-precipitation followed by sol–gel method. The structural and …

Owing to their excellent gas adsorption characteristics, titanium dioxide (TiO 2)
nanomaterials have been widely investigated for the detection of environmental volatile …

Heterojunction fabrication is an effective way to improve the performance of gas sensors. In
this work, NiO-modified ZnO nanoparticles and self-assembled nanosheets were prepared …

Foodborne pathogens like Listeria monocytogenes can cause various illnesses and pose a
serious threat to public health. They produce species-specific microbial volatile organic …

Abstract In this study, ZnO/In2O3-heterostructured nanosheets were prepared using a one-
step hydrothermal method. The effects of ZnO content on the gas-sensing performance were …
