摘要

热催化可以由于温度波动在热释电材料表面诱导正电荷和负电荷,并进一步产生活性氧驱动氧化还原反应,从而为缓解严重的环境污染和能源危机提供了一种潜在的解决方案。钙钛矿氧化物具有较高的安全性、环保性和结构可调节性,是热催化的理想催化剂。综述了钙钛矿氧化物热催化的研究进展。首先介绍了钙钛矿氧化物的热催化原理和热催化能量来源。然后,对提高钙钛矿氧化物热催化性能的策略进行了分类,包括控制形貌、电极化、构建相边界、引入氧空位、混合碳、包裹贵金属、利用多种催化协同作用和构建异质结构。随后,重点介绍了钙钛矿氧化物热催化的应用。最后,讨论了当前热催化领域面临的挑战,并展望了未来的发展前景。

A review of enhancement strategies for pyrocatalysis of perovskite oxides and their applications

Pyrocatalysis can induce positive and negative charges on the surface of pyroelectric materials owing to temperature fluctuations and can further generate reactive oxygen species to drive redox reactions, thus providing a potential solution to alleviate severe environmental pollution and energy crisis. Perovskite oxides are suitable catalysts for pyrocatalysis because of their high safety, environmental friendliness and structural adjustability. This review presents the research progress on pyrocatalysis of perovskite oxides. Firstly, the pyrocatalytic principle and the pyrocatalytic energy sources of perovskite oxides are introduced. Thereafter, strategies for enhancing the pyrocatalytic performance of perovskite oxides are categorized, including controlling morphology, electrical poling, constructing phase boundaries, introducing oxygen vacancies, mixing carbon, coating noble metals, leveraging multiple catalytic synergies and building heterostructures. Subsequently, the applications of perovskite oxide pyrocatalysis are focused. Finally, the current challenges in the field of pyrocatalysis are discussed, and future perspectives are provided.
