“…DFT calculations can provide a convenient and accurate way to predict the response performance of gas-sensing materials under ideal conditions, effectively reducing the costs and time associated with experimental trial and error. However, gas sensitivity in practical operations is influenced by complicated factors, such as temperature, pressure, humidity, concentration of target gas, and surface effects . The integration of theoretical analysis and experimental validation is crucial for achieving the efficient design of gas sensors with excellent sensitivity and selectivity.…”

The toxic gases emitted from industrial production have caused significant damage to the environment and human health, necessitating efficient gas sensors for their detection and removal. In this work, first-principles calculations are employed to investigate the potential application of diamanes for high-performance toxic gas sensors. The results show that nine gas molecules (CO, CO 2 , NO, NO 2 , NH 3 , SO 2 , N 2 , O 2 , and H 2 O) are physisorbed on pristine diamane by weak van der Waals interactions. After introducing H/F defects, diamane can effectively capture specific toxic gases (CO, NO, NO 2 , and SO 2 ) in the presence of interfering gases (N 2 , O 2 , and H 2 O), suggesting excellent selectivity and antiinterference ability. Orbital hybridization and significant charge redistribution between gas molecules and defective diamane dominate the enhanced adsorbate−substrate interactions. More importantly, the high sensitivity and good reversibility of defective diamane for detecting CO, NO, and SO 2 molecules enable its reuse as a superior resistance-type gas sensor. Our calculations provide valuable insights into the potential of defective diamane for detecting toxic gases and shed light on the practical application of novel carbon-based materials in the gas-sensing field.

“…Currently, humanity is experiencing an era of rapid development where daily life increasingly relies on high-tech and intelligent systems. However, this ongoing progress inevitably escalates the demand for energy and other resources, leading to environmental pollution issues, such as nitrogen oxides (NOx) [1,2], volatile organic compounds (VOCs) [3], sulfur dioxide (SO 2 ) [4], and heavy metal contamination in both air and water [5]. Research indicates that individuals residing in low socioeconomic areas face higher concentrations of air pollutants [6].…”

With the continuous acceleration of urbanization, air pollution has become an increasingly serious threat to public health. Strengthening the detection and control of pollutants has become a focal point in current society. In light of the increasing amount of literature in the field of air pollution control with every passing year, numerous reviews have been compiled; however, only a limited number employ bibliometric methods to comprehensively review and summarize research trends in this field. Herein, this study utilizes two bibliometric analysis tools, namely, CiteSpace (6.1.R6) and VOSviewer (1.6.20), to conduct a visual and comprehensive analysis of air pollution literature spanning 2000 to 2023. By doing so, it establishes a knowledge framework for research on air pollution control. Simultaneously, collaborative network analysis, reference co-citation network analysis, keyword co-occurrence network analysis, and keyword prominence are employed to undertake an exhaustive and profound visual examination within this domain. Results indicate that, over time, the number of relevant papers has exponentially increased, while interdisciplinary cooperation trends have gradually formed. Additionally, this study describes key areas of current research, including air pollution control residue treatment, regional joint air pollution control, and air pollution control mechanism analysis. Finally, challenges faced by researchers in this field and their different perspectives are discussed. To better integrate research findings on air pollution control, we explore the correlations among data and systematically present their developmental trends. This confirms the interdisciplinary nature of air pollution control research, in the hope of its guiding air pollution control in the future.
