In this study, novel ZnS@InS core@shell hollow nanospheres were fabricated by a facile refluxing method for the first time, and the formation mechanism of hollow structure with interior architecture was discussed based on ion-exchange Ostwald ripening. As the photocatalytic material for degradation of gaseous o-Dichlorobenzene (o-DCB), the as-synthesized core@shell hollow nanospheres were found to show significantly enhanced catalytic performance for effective separation of photo-generated charges. Moreover, the mechanisms of enhanced activity were elucidated by band alignment and unique configuration. Such photocatalyst would meet the demands for the control of persistent organic pollutant (POPs) in the atmospheric environment.
在本研究中，首次通过简便的回流法制备了新型ZnS@InS核壳空心纳米球，并基于离子交换奥斯特瓦尔德熟化讨论了具有内部结构的空心结构的形成机制。作为用于降解气态邻二氯苯（o-DCB）的光催化材料，所合成的核壳空心纳米球被发现对光生电荷的有效分离表现出显著增强的催化性能。此外，通过能带排列和独特构型阐明了活性增强的机制。这种光催化剂将满足大气环境中持久性有机污染物（POPs）控制的需求。
