Abstract

Within gas insulated switchgear (GIS), monitoring the breakdown of sulfur hexafluoride (SF₆), which serves as an insulating medium, is crucial for gauging the operational status of GIS and safeguarding equipment reliability. Our research introduces a novel material: ruthenium-modified α-AsP, designed to function as an adsorbent and sensor for key SF₆ decomposition gases—(SO₂, SOF₂, and SO₂F₂). Utilizing density functional theory (DFT), we explore the potential of α-AsP as a sensor or adsorbent for SF₆-derived gases. Our findings indicate that incorporating ruthenium enhances the response characteristics of the α-AsP monolayer to these decomposition gases. The high adsorption energy means that Ru-modified α-Asp may become a candidate material for gas sensors. This research also paves the way for future investigations into the gas-sensing properties of α-AsP.

Ru改性α-AsP SF6分解气体传感器传感性能的DFT研究

在气体绝缘开关设备（GIS）中，监测作为绝缘介质的六氟化硫（SF6）的击穿对测量GIS的运行状态和保障设备的可靠性至关重要。我们的研究介绍了一种新型材料：钌改性α-AsP，旨在作为SF6关键分解气体- （SO2， SOF2和SO2F2）的吸附剂和传感器。利用密度泛函理论（DFT），我们探索了α-AsP作为sf6衍生气体的传感器或吸附剂的潜力。研究结果表明，钌的加入增强了α-AsP单层对这些分解气体的响应特性。ru修饰的α-Asp具有较高的吸附能，可能成为气体传感器的候选材料。该研究也为进一步研究α-AsP的气敏性质铺平了道路。

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
