| 摘要: 实际废水中存在的离子会对有机污染物的光催化降解产生影响。以ZrCl4和2，5-二羟基对苯二甲酸为原料，通过水热合成法成功制备了金属有机骨架材料UIO-66-2OH。通过红外（IR）、X射线粉末衍射（XRD）、X射线光电子能谱（XPS）和扫描电子显微镜（SEM）对UIO-66-2OH的结构进行表征。利用水中常见的金属阳离子和无机阴离子，探索UIO-66-2OH的光催化性能。研究发现，金属阳离子Fe3+和无机阴离子HCO3-、CO32-可以加快光催化降解的速度。然而，金属离子Na+、K+、Ca2+、Mg2+、Cu2+和无机阴离子Cl-、SO42-、PO43-会抑制光催化性能，且离子价态越高，抑制效果越明显。 | |

| Abstract: Photocatalytic degradation of organic pollutants in actual wastewater requires exploring the influence of ions on the performance of photocatalysts. In this work, ZrCl4 and 2,5-dihydroxyterephthalic acid were used as raw materials, and the metal-organic framework material UIO-66-2OH was successfully prepared by the hydrothermal synthesis method. The structure of UIO-66-2OH was characterized by infrared (IR), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscope (SEM). The photocatalytic performance of UIO-66-2OH was explored by using common metal cations and inorganic anions in water. The studies have found that metal cations Fe3+ and inorganic anions HCO3-and CO32-can accelerate the rate of photocatalytic degradation. However, the metal ions Na+, K+, Ca2+, Mg2+, Cu2+ and inorganic anions Cl-, SO42-, PO43- can inhibit the photocatalytic performance, and the higher the ion valence, the more obvious the inhibition effect. | |
