Abstract

Single-atom metal catalysts (SACs) hold immense promise for catalytic applications, yet their potential as volatile organic compound (VOC) sensing materials remains largely untapped. Here, we report a facile approach to produce Cu single-atom (Cu-SA) embedded mesoporous carbon nitride (mCN) hybrid material for precise and selective detection of VOCs. The study highlights the exceptional sensing capabilities of Cu-SA-mCN, focusing on its remarkable selectivity for aliphatic esters, acids, and water molecules. Explicitly, the material demonstrates an exciting adsorption capacity of 109.4 mmol g⁻¹ for acetic acid, showcasing its superior performance, which is three times higher than mesoporous carbon nitride without Cu single atoms. The high selectivity and sensitivity of Cu-SA-mCN are attributed to the mesoporous nature, abundant nitrogen moieties, and Cu-SAs present within the material. Density functional theory (DFT) calculation results demonstrate a strong charge transfer between Cu-SA-mCN and adsorbate molecules, contributing to the material’s excellent sensing properties. This work opens new avenues in the development of mCN materials embedded with single metal atoms, enriching the field of VOC sensors with stable, accurate, and cost-effective solutions with potential applications in environmental monitoring and industrial safety.

铜单原子嵌入介孔氮化碳：一种用于VOC传感的杂化材料

单原子金属催化剂（SACs）具有巨大的催化应用前景，但其作为挥发性有机化合物（VOC）传感材料的潜力仍未得到充分开发。在这里，我们报告了一种简单的方法来生产Cu单原子（Cu- sa）嵌入的介孔氮化碳（mCN）杂化材料，用于精确和选择性地检测voc。该研究强调了Cu-SA-mCN的特殊传感能力，重点是其对脂肪酯、酸和水分子的显著选择性。结果表明，该材料对乙酸的吸附量为109.4 mmol g−1，是不含Cu单原子的介孔氮化碳的3倍。Cu-SA-mCN的高选择性和高灵敏度归因于材料的介孔性质、丰富的氮基团和cu - sa的存在。密度泛函理论（DFT）计算结果表明，Cu-SA-mCN与吸附质分子之间存在强烈的电荷转移，这有助于材料具有优异的传感性能。这项工作为开发嵌入单金属原子的mCN材料开辟了新的途径，丰富了VOC传感器领域，为环境监测和工业安全提供了稳定、准确和具有成本效益的解决方案。图形抽象

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
