As a typical n-type semiconductor, MoO has been widely applied in the gas-detection field due to its competitive physicochemical properties and ecofriendly characteristics. Volatile organic compounds (VOCs) are harmful to the atmospheric environment and human life, so it is necessary to quickly identify the presence of VOCs in the air. This review briefly introduced the application progress of an MoO-based sensor in VOCs detection. We mainly emphasized the optimization strategies of a high performance MoO, which consists of morphology-controlled synthesis and electronic properties functional modification. Besides the general synthesis methods, its gas-sensing properties and mechanism were briefly discussed. In conclusion, the application status of MoO in gas-sensing and the challenges still to be solved were summarized.
作为一种典型的n型半导体,由于其具有竞争力的物理化学性质和环境友好特性,MoO已在气体检测领域得到广泛应用。挥发性有机化合物(VOCs)对大气环境和人类生活有害,因此快速识别空气中VOCs的存在非常必要。本文综述简要介绍了基于MoO的传感器在VOCs检测中的应用进展。我们主要强调了高性能MoO的优化策略,包括形貌控制合成和电子性质功能修饰。除了一般的合成方法外,还简要讨论了其气敏性能和机理。最后,总结了MoO在气敏方面的应用现状以及仍需解决的挑战。
