Abstract

A novel, in situ, low-cost and facile method has been developed to fabricate flexible NO sensors capable of operating at ambient temperature, addressing the urgent need for monitoring this toxic gas. This technique involves the synthesis of highly porous structures, as well as the specific development of laser-induced graphene (LIG) and its heterostructures with SnO, all through laser scribing. The morphology, phases, and compositions of the sensors were analyzed using scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and Raman spectroscopy. The effects of SnO addition on structural and sensor properties were investigated. Gas-sensing measurements were conducted at room temperature with NO concentrations ranging from 50 to 10 ppm. LIG and LIG/SnO sensors exhibited distinct trends in response to NO, and the gas-sensing mechanism was elucidated. Overall, this study demonstrates the feasibility of utilizing LIG and LIG/SnO heterostructures in gas-sensing applications at ambient temperatures, underscoring their broad potential across diverse fields.

摘要

一种新颖的、原位的、低成本且简便的方法已被开发出来，用于制造能够在环境温度下工作的柔性NO传感器，以满足监测这种有毒气体的迫切需求。该技术涉及通过激光刻写合成高度多孔的结构，以及特定地开发激光诱导石墨烯（LIG）及其与SnO的异质结构。使用扫描电子显微镜、X射线衍射、X射线光电子能谱和拉曼光谱对传感器的形貌、相和组成进行了分析。研究了添加SnO对结构和传感器性能的影响。在室温下对浓度范围为50至10 ppm的NO进行了气敏测量。LIG和LIG/SnO传感器对NO表现出不同的响应趋势，并阐明了气敏机制。总体而言，这项研究证明了在环境温度下利用LIG和LIG/SnO异质结构进行气敏应用的可行性，突出了它们在不同领域的广泛潜力。
