The outbreak of the global pandemic has aroused significant attention from the public for healthy living environments. From this point of view, chemical sensors are crucial since these devices or actuators have diverse applications, such as environmental monitoring, food safety, industry, and healthcare. The development of chemical sensors may substitute human senses and precisely identify unspecified substances or discriminate materials accurately. For the implementation of chemical sensors utilized in daily life, there are requirements such as portability, low cost, low power consumption, high selectivity, and sensitivity. The most adequate materials are 2D materials that exactly agree with the described conditions. 2D materials have been studied for sensor applications owing to their unique material characteristics specialized for detecting particular substances. High surface to volume ratio or numerous reaction sites are representative physical properties of 2D materials. Furthermore, high carrier mobility is a typical feature of these substances appropriate for manufacturing advanced chemical sensors. Herein, the history and recent advances of 2D material‐based chemical sensors along with a description of perspectives and future challenges are introduced. This review provides a guideline for preparing chemical sensors based on 2D materials as next‐generation sensing devices.

“… 165 The shift in the resonance wavelength upon exposure to the gas was correlated to the methane concentration in the range of 10–100 ppm. Other optical sensing methods based on midinfrared light emitting diodes, 166 refractive index-modulated optical fiber systems, 167 photoacoustic spectroscopy, 168 and photoelectrochemical detection 169 have been demonstrated for methane quantification. In addition to optical sensing, methane detectors based on QCM 170 and SAW 171 have been developed, but their complexity in device design and user training has so far limited their applications in the mining sector.…”

“…There is a plethora of further studies on exotic applications of CNTs and structures with enhanced properties for gas sensing, portability, or low-power operation [ 75 ]. Similar to the CNT, graphene-based yarn architectures have been shown to be a potential solution for self-powered photoelectrochemical sensing of methane [ 76 ]. CNTs have also been interwoven in three-dimensional (3D)-printed fabrics to spearhead a new generation of portable electronics [ 77 ].…”

During the last few decades, the microelectronics industry has actively been investigating the potential for the functional integration of semiconductor-based devices beyond digital logic and memory, which includes RF and analog circuits, biochips, and sensors, on the same chip. In the case of gas sensor integration, it is necessary that future devices can be manufactured using a fabrication technology which is also compatible with the processes applied to digital logic transistors. This will likely involve adopting the mature complementary metal oxide semiconductor (CMOS) fabrication technique or a technique which is compatible with CMOS due to the inherent low costs, scalability, and potential for mass production that this technology provides. While chemiresistive semiconductor metal oxide (SMO) gas sensors have been the principal semiconductor-based gas sensor technology investigated in the past, resulting in their eventual commercialization, they need high-temperature operation to provide sufficient energies for the surface chemical reactions essential for the molecular detection of gases in the ambient. Therefore, the integration of a microheater in a MEMS structure is a requirement, which can be quite complex. This is, therefore, undesirable and room temperature, or at least near-room temperature, solutions are readily being investigated and sought after. Room-temperature SMO operation has been achieved using UV illumination, but this further complicates CMOS integration. Recent studies suggest that two-dimensional (2D) materials may offer a solution to this problem since they have a high likelihood for integration with sophisticated CMOS fabrication while also providing a high sensitivity towards a plethora of gases of interest, even at room temperature. This review discusses many types of promising 2D materials which show high potential for integration as channel materials for digital logic field effect transistors (FETs) as well as chemiresistive and FET-based sensing films, due to the presence of a sufficiently wide band gap. This excludes graphene from this review, while recent achievements in gas sensing with graphene oxide, reduced graphene oxide, transition metal dichalcogenides (TMDs), phosphorene, and MXenes are examined.
