摘要

氡（Rn）检测对环境安全至关重要，但开发高效的传感材料仍然是一个挑战。本文采用离散傅里叶变换研究了掺杂石墨烯结构be -石墨烯、p -石墨烯、si -石墨烯和s -石墨烯对Rn的吸附。研究结果表明，be -石墨烯相互作用最强，转移电荷最多，使这种材料成为氡吸附的主要候选者，特别是在电场存在的情况下。在此过程中，Be-Graphene将在氡传感和修复方面引入有希望的进展。这项工作为调整石墨烯基材料用于下一代环境监测技术的气敏应用提供了理论基础。

Theoretical study of radon adsorption on doped graphene for environmental safety applications

Radon (Rn) detection is vital for environmental safety, yet the development of highly effective sensing materials remains a challenge. This paper employs DFT to study Rn adsorption on doped graphene structures: Be-Graphene, P-Graphene, Si-Graphene, and S-Graphene. The findings indicate that Be-Graphene interacts the strongest and transfers the most charges, making this material a prime candidate for radon adsorption, especially in the presence of an electric field. In doing so, Be-Graphene is set to introduce promising advancements in radon sensing and remediation. This work supplies the theoretical basis for tuning graphene-based materials for gas sensing applications toward the next generation of environmental monitoring technologies.

期刊介绍： The Journal of Environmental Radioactivity provides a coherent international forum for publication of original research or review papers on any aspect of the occurrence of radioactivity in natural systems. Relevant subject areas range from applications of environmental radionuclides as mechanistic or timescale tracers of natural processes to assessments of the radioecological or radiological effects of ambient radioactivity. Papers deal with naturally occurring nuclides or with those created and released by man through nuclear weapons manufacture and testing, energy production, fuel-cycle technology, etc. Reports on radioactivity in the oceans, sediments, rivers, lakes, groundwaters, soils, atmosphere and all divisions of the biosphere are welcomed, but these should not simply be of a monitoring nature unless the data are particularly innovative.
