摘要

采用水热法制备了z型LaCoO3/ZnO (LCZ)异质结光催化剂。在光催化降解盐酸四环素中，LCZ表现出最高的光催化活性，速率常数为0.0179 min−1，分别是纯ZnO和LaCoO3的3.2和2.3倍。该研究为光催化降解领域提供了一种具有潜在应用前景的方法。进一步的理论研究表明，z型异质结的存在可以防止电子-空穴对的复合，从而提高光催化性能。

Construction of Z-scheme heterojunction LaCoO3 modified ZnO for photocatalytic degradation of tetracycline under visible light irradiation

The Z-scheme LaCoO₃/ZnO (LCZ) heterojunction photocatalyst was designed and prepared using the hydrothermal method. In the photocatalytic degradation of tetracycline hydrochloride, LCZ exhibited the highest photocatalytic activity with a rate constant of 0.0179 ${min}^{- 1}$ ,which is 3.2 and 2.3 times higher than those of pure ZnO and LaCoO₃, respectively. This study presents a promising approach with potential applications in the field of photocatalytic degradation. Further theoretical studies reveal that the existence of Z-scheme heterojunction can prevent the recombination of electron-hole pairs, leading to enhanced photocatalytic performance.
