Sensors, capable of detecting trace amounts gas molecules or volatile organic compounds (VOCs), are in great demand for environmental monitoring, food safety, health diagnostics, and national defense. In the era Internet Things (IoT) big data, requirements on sensors, addition to sensitivity selectivity, have been increasingly placed sensor simplicity, room temperature operation, ease integration, flexibility. The key meet these is development high-performance sensing materials. Two-dimensional (2D) atomic crystals, emerged after graphene, demonstrated a number attractive properties that beneficial sensing, such as versatile tunable electronic/optoelectronic metal chalcogenides (MCs), rich surface chemistry good conductivity MXenes, anisotropic structural electronic black phosphorus (BP). While most sensors based 2D crystals incorporated setup chemiresistor, field-effect transistor (FET), quartz crystal microbalance (QCM), optical fiber, their working principles involve adsorption, charge transfer, reaction, mass loading, and/or change refractive index vary from material material. Understanding gas-solid interaction subsequent signal transduction pathways essential not only improving performance existing materials but also searching new advanced ones. this review, we aim provide an overview recent various both experimental theoretical investigations. We will particularly focus mechanisms related well approaches enhance performances. Finally, summarize whole article future perspectives with

In this work, a novel light-modulated bifunctional gas sensor based on Au nanoparticles-modified 2D InSe nanosheets was demonstrated. The prepared displayed reversible and extremely high response for recognition of nitrogen dioxide (NO2) under visible-light illumination. sensitivity (1192%) about 10 times higher than that dark condition, the limit detection (LOD) 0.17 ppb. contrast, when sensing ammonia (NH3), selectivity were obtained in darkness rather light, with LOD 11% 0.2 ppm. Furthermore, possesses decent stability, repeatability, anti-interference ability. tunable behavior light modulation has been clearly studied help density functional theory. A new principle called "carrier storage box" nanoparticles proposed to explain change surface state modulation. Finally, successfully applied construct fully integrated wearable device measure NH3 NO2 ambient environment. all, work provides highly competitive method paves way designing materials-based optoelectronic devices multifunctional features.
