Butanone is a precursor chemical and detrimental to human body, as a consequence, it is
significant for social stability to accurately detect trace butanone. In this paper, Co 3 O 4/SnO …

The development of gas sensors with high selectivity to volatile ketones at low temperature
has recently been a hot topic. However, the reported good response to butanone is usually …

Transition metal (TM) elements are often applied through doping to improve sensor
performance for the detection of toxic and hazardous gases. Elemental valence conversion …

The indiscriminate production and use of antibiotics have caused an environmental
imbalance. Therefore, advanced oxidative processes such as photocatalysis have been …

Abstract Cuboid-shaped SnO 2 and Ce-doped SnO 2 materials with different Ce amounts
(0.5 at%, 1 at%, 3 at%, and 5 at%) were successfully prepared via an environmentally …

The urgency of early lung cancer (LC) diagnosis and treatment has been more and more
significant. Exhaled breath analysis using gas sensors is a promising way to find out if …

In recent years, researchers have discovered that self-assembled monolayer functionalized
surfaces could improve the gas-sensing performance of semiconductor oxide-based …

Developing a device or material to detect volatile organic compounds (VOC) is no longer a
challenge, despite its great interest. The difficulty is linked to developing a material that does …

Sensors of volatile organic compounds (VOCs) are of great importance for environmental
monitoring. Nevertheless, it is a great challenge to develop highly sensitive and selective …
