湿式压电催化技术在去除大气中含硫挥发性有机物方面的应用研究较少。在此，银簇沉积在BaTiO 3纳米棒（NR）与电子金属支持相互作用（EMSI）合成的压电催化消除的代表性的S-VOC，CH 3SH在湿式洗涤反应器。Ag/BaTiO_3纳米棒对CH_3SH的压催化氧化活性有明显的提高，对SO_42-的去除率为92.0%，选择性为76.7%。Ag含量，压电电位的BaTiO 3基板，和湿法洗涤工艺被证实是至关重要的催化活性。基于对BaTiO 3、Ag/BaTiO 3 NR和Ag/BaTiO 3纳米颗粒（NPs）的实验分析和有限元方法模拟，Ag/BaTiO 3 NR的上级压电催化活性可以归因于均匀分散的Ag物种增强了CH 3 SH的捕获，BaTiO 3 NR比NPs更大的压电电势，Ag和BaTiO 3之间的EMSI有效地促进了压电电子的迁移，并增强了湿法洗涤过程中的质量扩散。我们对压电效应在S-VOC去除中的重要性的发现为设计用于VOC净化的高性能催化剂提供了新的选择。
The application of wet-piezotronic catalysis is rarely investigated in eliminating sulfur-containing volatile organic compounds (S-VOCs) in the atmosphere. Herein, Ag clusters deposited on BaTiO3nanorods (NRs) with electronic metal–support interaction (EMSI) were synthesized for the piezocatalytic elimination of a representative S-VOC, CH3SH in a wet scrubbing reactor. The Ag/BaTiO3NRs showed an obvious enhancement of piezocatalytic activity for oxidizing CH3SH to the less-toxic products with a removal rate of 92.0% and a selectivity of 76.7% toward SO42–. The Ag content, piezoelectric potential of the BaTiO3substrate, and wet scrubbing process are confirmed to be vital to the catalytic activity. Based on the experimental analysis and finite element method simulation for BaTiO3, Ag/BaTiO3NRs, and Ag/BaTiO3nanoparticles (NPs), the superior piezocatalytic activity of the Ag/BaTiO3NRs can be attributed to the uniformly dispersed Ag species that enhanced the capture of CH3SH, the larger piezoelectric potential of BaTiO3NRs than that of NPs, the EMSI between Ag and BaTiO3that effectively promoted the migration of piezoelectric electrons, and the enhanced mass diffusion in the wet scrubbing process. Our discovery of the significance of piezoelectric effects in S-VOC removal offers a new option to design high-performance catalysts for VOC purification.
