NO 2 is an oxidizing gas, which is considered to be the most dangerous and most toxic gas
that should be controlled. Because of the advantages of high sensitivity, selectivity, stability …

The release of toxic and harmful gases seriously endangers human health and social and
environmental safety. Sensitive determination of these gases is urgently needed to meet the …

With the rapid development of the Internet of Things, there is a great demand for portable
gas sensors. Metal oxide semiconductors (MOS) are one of the most traditional and well …

The gas sensor made of two-dimensional (2D) material heterojunction has superior gas
sensitivity, but the response mechanism has not been systematically investigated for a long …

Breathing is an inherent human activity; however, the composition of the air we inhale and
gas exhale remains unknown to us. To address this, wearable vapor sensors can help …

Single‐atom catalysts (SACs) attract extensive attention in the field of heterogeneous
catalysis in recent years due to the maximum atom utilization and unique physical and …

Recently, Ti3C2Tx MXenes have begun to receive attention in the field of gas sensors owing
to their characteristics of high conductivity and abundant surface functional groups …

Abstract Two-dimensional (2D) transition metal dichalcogenides (TMDs) hold great promise
for room temperature (RT) NO 2 sensors. However, the exposure of the edges of TMDs with …

Timely detection of formaldehyde is pivotal because formaldehyde is slowly released from
the indoor decorative materials, jeopardizing our healthy. Herein, a high-response …

The unique properties of heterostructure materials make them become a promising
candidate for high-performance room-temperature (RT) NO 2 sensing. Herein, a pn …
