In recent times, nanomaterials have been applied for the detection and sensing of toxic gases in the environment owing to their large surface-to-volume ratio and efficiency. CO 2 is a toxic gas that is associated with causing global warming, while SO 2 and NO 2 are also characterized as nonbenign gases in the sense that when inhaled, they increase the rate of respiratory infections. Therefore, there is an explicit reason to develop efficient nanosensors for monitoring and sensing of these gases in the environment. Herein, we performed quantum chemical simulation on a Ca 12 O 12 nanocage as an efficient nanosensor for sensing and monitoring of these gases (CO 2 , SO 2 , NO 2 ) by employing high-level density functional theory modeling at the B3LYP-GD3(BJ)/6-311+G(d,p) level of theory. The results obtained from our studies revealed that the adsorption of CO 2 and SO 2 on the Ca 12 O 12 nanocage with adsorption energies of −2.01 and −5.85 eV, respectively, is chemisorption in nature, while that of NO 2 possessing an adsorption energy of −0.69 eV is related to physisorption. Moreover, frontier molecular orbital (FMO), global reactivity descriptors, and noncovalent interaction (NCI) analysis revealed that the adsorption of CO 2 and SO 2 on the Ca 12 O 12 nanocage is stable adsorption, while that of NO 2 is unstable adsorption. Thus, we can infer that the Ca 12 O 12 nanocage is more efficient as a nanosensor in sensing CO 2 and SO 2 gases than in sensing NO 2 gas.

“…With the gradual exhaustion of fossil energy, the utilization of renewable energy (e.g., wind power and hydropower) is one of the most effective ways to solve the global energy crisis. [162][163][164][165] The compatibility of NGs also gives them considerable advantages in energy harvesting in the environment. Figure 12d shows a TENG sensor based on 2D ZnO nanowire array that collects heat from the environment and converts it into electricity.…”

With the development of the Internet of Things, there is an increasing need for clean energy and large-scale sensory systems. Triboelectric/piezoelectric nanogenerators (TENGs/PENGs), have attracted considerable attention as a new type of power generation terminal, which can harvest surrounding energy and convert it into electrical energy. To improve the output performance of nanogenerators (NGs) and diversify related applications, 2D materials with high carrier mobility and excellent piezoelectric properties can be directly used or integrated as different types of self-powered sensors. In this review, the authors first introduce the excellent piezoelectric and optoelectronic properties of 2D materials, followed by the triboelectric series of 2D materials used in TENGs. The categories of integrated self-powered sensors based on 2D materials are then summarized according to their different structures and compositions. We also discuss in detail the recent applications of integrated self-powered sensors based on 2D materials from five aspects. Finally, the challenges and outlooks in the research field of self-powered sensors are featured. Given the continuous development of self-powered sensors based on 2D materials, they are considered to have significant potential for applications in biomedicine, environmental detection, human motion monitoring, energy harvesting, and smart wearable devices.

“…[7][8][9] In recent years, twodimensional (2D) van der Waals (vdW) heterostructure-based solar cells have been proposed due to their high carrier mobilities, significant absorption coefficients, and designabilities. [10][11][12] For example, Ti 2 CO 2 /Zr 2 CO 2 13 and BP/SnSe 14 vdW heterostructures have been proved to have anisotropy carrier mobilities of more than 10 3 cm 2 V À1 s À1 . The absorption coefficients of the AsI 3 /SbI 3 and GaSe/GaTe 16 vdW heterostructures reach up to B10 5 cm À1 .…”
