Abstract One-dimensional SmVO4 rods have been effectively prepared by a metal organic framework (MOF) assisted solvothermal method using 2-methyl imidazole as an organic linker. The rod-like SmVO4 was systematically investigated using X-ray diffraction technique (XRD), transmission electron microscopy (TEM), X-Ray photoelectron spectroscopy (XPS), and UV-visible DRS techniques. The tetragonal phase SmVO4 catalyst exhibits an outstanding photocatalytic efficiency with a removal rate of 95% towards the removal of tetracycline under visible light. The SmVO4 catalyst still shows an elevated photocatalytic removal rate even after three consecutive cycles of usage. This infers the incentive for stability and reusability of the SmVO4 catalyst prepared by the MOF route.

一步 MOF 辅助合成 SmVO4 纳米棒在可见光下光催化降解四环素

摘要 以 2-甲基咪唑为有机连接体，通过金属有机骨架 (MOF) 辅助溶剂热法制备了一维 SmVO4 棒。使用 X 射线衍射技术 (XRD)、透射电子显微镜 (TEM)、X 射线光电子能谱 (XPS) 和紫外可见 DRS 技术系统地研究了棒状 SmVO4。四方相SmVO4催化剂表现出出色的光催化效率，在可见光下对四环素的去除率为95%。即使在连续三个循环使用后，SmVO4 催化剂仍显示出较高的光催化去除率。这推断出通过 MOF 路线制备的 SmVO4 催化剂的稳定性和可重复使用性的动机。
