The Cu(II) metal-organic frameworks (MOFs) based on 1,3,5-benzenetricarboxylic acid (Cu(BTC)) was synthesized by the hydrothermal method. The synthesized Cu(BTC) exhibited pyramid-shaped morphology and showing an average specific area of 32.16 m g. The Cu(BTC) photocatalysts were characterized using Fourier-transform infrared spectroscopy (FTIR), powder X-ray diffraction (PXRD), field emission scanning electron microscopy-energy-dispersive X-ray spectroscopy (FESEM-EDX), UV-Vis diffusive reflectance spectra, and Brunauer-Emmett-Teller (BET). The photocatalytic activity of Cu(BTC) was examined on Rhodamine B (RhB) degradation under visible light irradiation. The outcomes displayed exceedingly enhanced photocatalytic activity under visible light. In addition, its recyclability was also confirmed for multiple cycles. The easiness of construction and high photocatalytic performance of Cu(BTC) photocatalysts can be capable in environmental applications to treat water contamination.
基于 1,3,5-苯三甲酸（Cu(BTC)）的 Cu(II) 金属有机骨架（MOFs）通过水热法合成。合成的 Cu(BTC) 呈现出金字塔形形态，比表面积平均为 32.16 m²/g。使用傅里叶变换红外光谱（FTIR）、粉末 X 射线衍射（PXRD）、场发射扫描电子显微镜-能谱仪（FESEM-EDX）、紫外可见漫反射光谱和 Brunauer-Emmett-Teller（BET）对 Cu(BTC) 进行了表征。在可见光照射下，考察了 Cu(BTC)对罗丹明 B（RhB）降解的光催化活性。结果表明，在可见光下表现出极高的光催化活性。此外，还证实了其在多次循环中的可回收性。Cu(BTC)光催化剂结构简单，光催化性能高，可用于环境应用以处理水污染。
