Defect engineering constitutes a widely-employed method of adjusting the electronic structure and properties of oxide materials. However, controlling defects at room temperature remains a significant challenge due to the considerable thermal stability of oxide materials. In this work, a facile room-temperature lithium reduction strategy is utilized to implant oxide defects into perovskite BaTiO (BTO) nanoparticles to enhance piezocatalytic properties. As a potential application, the piezocatalytic performance of defective BTO is examined. The reaction rate constant increases up to 0.1721 min, representing an approximate fourfold enhancement over pristine BTO. The effect of oxygen vacancies on piezocatalytic performance is discussed in detail. This work gives us a deeper understanding of vibration catalysis and provides a promising strategy for designing efficient multi-field catalytic systems in the future.
缺陷工程是一种广泛应用于调节氧化物材料电子结构和性能的方法。然而，由于氧化物材料具有相当高的热稳定性，在室温下控制缺陷仍然是一项重大挑战。在这项工作中，采用了一种简便的室温锂还原策略，将氧化物缺陷引入钙钛矿钛酸钡（BTO）纳米颗粒中，以增强其压电催化性能。作为一种潜在应用，对有缺陷的BTO的压电催化性能进行了研究。反应速率常数提高到0.1721 min，比原始BTO提高了约四倍。详细讨论了氧空位对压电催化性能的影响。这项工作使我们对振动催化有了更深入的理解，并为未来设计高效的多场催化系统提供了一种有前景的策略。
