Along with the revolution of Internet Things (IoT), smart, flexible, easily fabricated, and highly sensitive gas sensors are essential for many portable electronics. In this study, a wearable NO2 sensor based on nanomesh structure woven Ti3C2Tx microflakes Bi2S3 nanobelts operated at room temperature was successfully designed prepared. The effects mass ratio between two materials performance were evaluated. embedded inside accordion-like provide large specific surface areas abundant active sites adsorption molecules. Attributed to high conductivity Ti3C2Tx, carriers generated in layers transmitted during sensing, thus significantly reducing response recovery times. containing 30 wt % exhibits excellent sensing performance, fast response/recovery rates, stability even arbitrary deformed shape conditions. Upon exposure 1 ppm NO2, is 12.67, times 5/28 s, respectively. A stable can be maintained after 1500 cycles deformation. This work demonstrates simple but reliable manufacturing strategy next generation IoT monitoring network-linking human activities.

Functionalization by noble metal catalysts and the construction of heterojunctions are two effective methods to enhance gas sensing performance oxide-based sensors. In this work, we adopt porous ZIF-8 as a catalyst substrate encapsulate ultra-small Pt nanoparticles. The Pt/ZnO-In2O3 hollow nanofibers derived from Pt/ZIF-8 were prepared facile electrospinning method. 25PtZI HNFs sensor possessed response value 48.3 100 ppm HCHO, 2.7 times higher than pristine In2O3, along with rapid response/recovery time (5/22 s), lower theoretical detection limit (74.6 ppb). improved properties can be attributed synergistic effects electron sensitization catalytic nanoparticles, high surface O− absorbing capability heterojunctions. present study paves new way design formaldehyde sensors in practical application.

Abstract 2D nanomaterials have triggered widespread attention in sensing applications. Especially for layered metal chalcogenides (LMCs), the unique semiconducting properties and high surface area endow them with great potential gas sensors. The assembly of LMCs guest species is an effective functionalization method to produce synergistic effects hybridization greatly enhancing gas‐sensing properties. This review starts synthetic techniques, properties, principles, then comprehensively compiles advanced achievements pristine Key advances development are categorized according spatial architectures. It systematically discussed three aspects: surface, lattice, interlayer, comprehend benefits functionalized from chemical effect, electronic structure features. challenges outlooks developing high‐performance LMCs‐based sensors also proposed.
