- W3155087194 abstract "Silicon nanowires (SiNWs) is considered as one of the most promising candidates for gas sensing application due to its capability of operating at room temperature (20 °C) and compatibility with modern semiconductor process. However, there still remains a challenge that SiNWs is poorly sensitive to volatile organic compounds (VOCs). In this study, we reveal that the co-decoration of zeolite imidazole frameworks-8 (ZIF-8) and Ag nanoparticles can improve the gas-sensing response to ethanol and enhance the humidity resistance at 20 °C. Due to the inversion modulation introduced by nano-Ag modificaiton and the enhanced gas adsorption provided by ZIF-8 modification, the resultant co-decorated sensor of ZIF-8&[email protected] shows obviously enhanced response upon exposure to ethanol with wide concentration range. It meanwhile exhibits a practical capability to sense rarefied ethanol vapor low to 125 ppb at 20 °C and relative humidity of 25 %. Especially, the sensor exhibits a low limit of detection of 5.45 ppb of ethanol vapor. When working at high humidity of 85 %, the developed ZIF-8&[email protected] sensor still remain a significant response. The superior moisture resistance performance is clarified by first-principles caculations to be highly related to the hydrophobicity characteristic of the modified ZIF-8 and the hygroscopic center formed by Ag nanoparticles. A resistance model was proposed to demonstrate the enhanced sensing response of the ZIF-8&[email protected] Further, a two-level moisture resistance mechanism is demonstrated based on the first-principles caculations and the unique microstructure of ZIF-8&[email protected] The beneficial effect of ZIF-8&nano-Ag co-modification demonstrated in present work suggest an effective strategy for developing superior gas sensors capable of sensitive detection of VOCs with strong stability in humditiy ambient." @default.
