Investigations into the mechanisms governing the behavior of metal oxide gas sensors
continue to be of great interest. Oxygen vacancies are a ubiquitous defect in this class of …

The oil spill pollution has become one of the most significant threats to the marine
environment and coastal ecology. An efficient way is urgently expected to remove the oil …

Low-power metal oxide (MOX)-based gas sensors are widely applied in edge devices. To
reduce power consumption, nanostructured MOX-based sensors that detect gas at low …

Designing composite nanomaterials is one of the most important key techniques for
improving gas sensing performance. In this paper, a design of the ethanol sensor based on …

The density of oxygen vacancies in semiconductor gas sensors was often assumed to be
identical throughout the grain in the numerical discussion of the gas-sensing mechanism of …

Triethylamine (TEA) is widely viewed as the toxic volatile organic compounds and causes a
severe risk to environmental protection and human health. However, the current sensors are …

Oxygen vacancy (VO) is long believed as a key factor influencing the gas sensing
properties. However, the concentration of VO is generally focused while the VO state is …

In this study, we have successfully fabricated high-performance trimethylamine (TMA)
sensors. Defect-engineering (DE) strategy in which two organic ligands, ie, dicarboxylate …

For traditional resistance-type gas sensor, introducing heterostructures was an effective way
to enhance the sensing performance. In this work, heterostructure In 2 O 3/ZnS composites …

Nobel metal modification could be a valuable method for the fabrication of advanced
