Confine and eliminate: The integration of ZnO nanoparticles and CeO_x nanoparticles into hollow microspheres (ZnO/CeO_x HMS) could provide broad-spectrum UV protection and scavenge reactive oxygen species (ROS) generated under UV irradiation (see figure). Benefiting from the cooperative effect of the hollow structure and the antioxidative enzyme mimicking activity of CeO_x, the generated ROS could be confined to the limited space and effectively scavenged.

将活性氧限制在基于人工酶的空心结构中，以消除光催化剂对紫外线滤光片的不利影响

限制并消除：将ZnO纳米颗粒和CeO _x纳米颗粒整合到空心微球（ZnO / CeO _x HMS）中可以提供广谱的紫外线防护，并清除在紫外线照射下产生的活性氧（ROS）（见图）。从所述中空结构的协同效应和抗氧化酶的CeO极似活性受益_X，所产生的ROS可能被限制在有限的空间和有效地清除。
