This contribution reports the synthesis of mesoporous X% Nd₂O₃ modified ZnO (X = 1, 2, 3 and 4) during sol-gel process in existence of Pluronic F-108 for the first time. XRD indicated the construction of hexagonal ZnO nanocrystals and the isotherms exhibited of type IV with a type H2 hysteresis loop, indicating the existence of mesostructures. The synthesized samples were evaluated by photodegradation of tetracycline (TC) in visible light exposure compared to pure mesoporous ZnO nanoparticles (NPs) and commercial photocatalyst P-25. The photocatalytic efficiency mesoporous 3%Nd₂O₃/ZnO for degradation TC reached up to 100 % for 2 h compared to pure mesoporous ZnO and P-25 with 4 and 10 %, respectively. The mesoporous 3%Nd₂O₃/ZnO photocatalysts showed promoted photocatalytic performance, resulting in an improved photodegradation rate value up to 8.8 and 16.3 times that of compared to pure ZnO and P-25, which was explained by better photogenerated charge carriers separation as a result of heterojunction construction between Nd₂O₃ and ZnO interfaces. In addition, the 3%Nd₂O₃/ZnO photocatalysts showed sufficient stability for five repeated runs and created its potential utility for mitigation of organic pollutants in comparison to pure ZnO and commercial P-25.

该贡献报告首次在存在Pluronic F-108的溶胶-凝胶过程中合成了介孔X％Nd ₂ O ₃修饰的ZnO（X = 1、2、3和4）。XRD表明六角形的ZnO纳米晶体的构造，并且等温线显示为IV型，具有H2型磁滞回线，表明存在介观结构。与纯中孔ZnO纳米颗粒（NPs）和市售光催化剂P-25相比，在可见光照射下通过四环素（TC）的光降解来评估合成的样品。与纯中孔ZnO和P-25分别为4％和10％相比，中孔3％Nd ₂ O ₃ / ZnO降解TC的光催化效率最高可达100％，持续2 h。介孔3％Nd₂ O ₃ / ZnO光催化剂显示出增强的光催化性能，与纯ZnO和P-25相比，光降解率值提高了8.8倍和16.3倍，这可以解释为异质结结构可改善光生电荷载流子的分离在Nd ₂ O ₃和ZnO界面之间。此外，与纯ZnO和市售P-25相比，3％Nd ₂ O ₃ / ZnO光催化剂显示了五次重复运行的足够稳定性，并产生了缓解有机污染物的潜在效用。
