摘要

在此，我们首次将聚氧化物金属盐（POMs）作为电子受体引入到典型的气敏材料 Cr2O3 中。我们制作了一系列 Cr2O3/PW12 复合气体传感器。对乙醇蒸汽的传感特性进行了研究。优化后的 Cr2O3/5%PW12 传感器对 100 ppm 乙醇的响应为 7.65，远高于纯 Cr2O3。这种改进可归因于两种成分之间的协同效应。作为电子受体，PW12 促进了载流子在 PW12 和 Cr2O3 之间的迁移，从而提高了 Cr2O3 的气体传感性能。这项工作促进了聚氧化金属酸盐在传感领域的实际应用。

Modification of chromium oxide nanofibers by polyoxometalate electron acceptor doping for enhancement of ethanol gas detectability

Herein, we introduced polyoxometalates (POMs) as electron acceptors into a typical gas sensitive material Cr₂O₃ for the first time. A series of Cr₂O₃/PW₁₂ composite gas sensors were fabricated. The sensing properties to ethanol vapor were studied. The optimized Cr₂O₃/5%PW₁₂ sensor exhibited a response of 7.65 to 100 ppm ethanol, which is much higher than pure Cr₂O₃. The improvement can be attributed to the synergistic effect between the two components. As an electron acceptor, PW₁₂ promotes carrier migration between PW₁₂ and Cr₂O₃, thereby improving the gas sensing performance of Cr₂O₃. This work promotes the practical application of polyoxometalate in sensing field.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
