Abstract

In this research, we explored the hydrogen gas sensing properties of microwave-reduced graphene oxide (M-rGO) along with rGO-SnO₂ and rGO-ZnO nanohybrids. These nanohybrids were prepared through a microwave treatment process. Their structural and optical characteristics were analyzed using X-ray diffraction, field emission scanning electron microscopy, and UV-Visible spectroscopy, confirming the successful formation of graphene-metal oxide hybrid structures. The hydrogen gas detection performance of the rGO-SnO₂ and rGO-ZnO nanohybrids was evaluated by subjecting their thin-film sensing platforms to varying concentrations of hydrogen gas (from 50 ppm down to 0.1 ppm) at an operating temperature of 150 °C. The resistance-time behavior of the nanohybrids was monitored under both hydrogen exposure and normal conditions, with measurements taken using a Keithley 2461 source meter. Sensitivity measurements showed maximum values of 22.07%, 22.85%, and 79.39% for M-rGO, rGO-SnO₂, and rGO-ZnO platforms, respectively. These findings were supported by theoretical simulations based on density functional theory (DFT) performed with the Quantum ATK-Synopsis code (version 19.03). The study demonstrates the superior hydrogen sensing capability of the rGO-ZnO nanohybrid.

ZnO-/ sno2 -石墨烯纳米杂化体上H2气体的高效检测:实验和DFT研究
在这项研究中,我们探索了微波还原氧化石墨烯(M-rGO)以及rgo - sno2和rGO-ZnO纳米杂化物的氢气传感性能。这些纳米杂化物是通过微波处理工艺制备的。利用x射线衍射、场发射扫描电镜和紫外可见光谱分析了它们的结构和光学特性,证实了石墨烯-金属氧化物杂化结构的成功形成。通过将rGO-SnO 2和rGO-ZnO纳米杂化物的薄膜传感平台置于不同浓度的氢气(从50 ppm到0.1 ppm)下,在150°C的工作温度下,评估了它们的氢气检测性能。采用Keithley 2461源计对纳米杂化材料在氢气暴露和正常条件下的电阻时间行为进行了监测。M-rGO、rgo - sno2和rGO-ZnO平台的灵敏度分别为22.07%、22.85%和79.39%。这些发现得到了基于密度泛函理论(DFT)的理论模拟的支持,这些理论模拟是用Quantum atk - synosis代码(19.03版本)进行的。该研究证明了氧化石墨烯-氧化锌纳米杂化材料具有优越的氢传感能力。

期刊介绍: The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
