A dog nose-inspired high-performance NH3 gas sensor of biomass carbon materials with a pleated structure derived from rose tea

Abstract: Inspired by the similarity between the pleated structure of rose petals and the pleated structure of dog’s maxillary turbinate, porous biomass carbon materials with pleated structure are successfully prepared from...

“…fabricated porous carbon materials from rose tea (CRT) as chemical sensors for NH 3 gas detection. [ 392 ] The SEM images of CRT with different resolutions in Figure 19 a suggest that CRT has a pleated nanostructure similar to the internal rugae structure of the dog nose. CRT shows a high response (60.16 k%) to NH 3 gas of 500 ppm (Figure 19b ), and the theoretical limit of detection is calculated to be 4.82 ppb.…”

“…Metal oxide semiconductor (MOS)-based gas sensors have shown wide application prospects in the detection of inflammable and explosive gases, environmental pollution, toxic gases, and VOCs, especially in the field of human-disease monitoring based on oral exhaled breath detection, due to their advantages of high sensitivities, small sizes, real-time measurement capabilities, low costs, and portability. , Among the H 2 S-gas-sensitive materials studied, Cu 2 O stands out due to its high chemical affinity for sulfur components, which is not only conducive to improving the sensitivity of the materials but also guarantees the selectivity by preventing cross-reactions with other gases. In addition, to further improve the gas sensitivity, many researchers have prepared composite materials through the interactions of Cu 2 O with other nanoscale components, thereby achieving better performance than the sum of the individual components.…”

“…The rapid expansion of the global population and significant development in industrialization emerged as critical factors that contributed to the rapid aggravating of air pollution, leading to detrimental effects on human health and the environment. Therefore, the real-time monitoring of these gases assumed great significance as it enabled the timely implementation of preventive measures, ensuring the safety of both individuals and the environment. The development of gas-sensing technology made a substantial contribution to environmental monitoring, industrial production, medical diagnosis, etc. Therefore, there is an increasing demand for high-performance gas sensor devices.…”
