In this study, a flower-like BiVO/MIL-101-NH composite is synthesized by a facile and surfactant-free process. The -COO-Bi ionic bond construction was conductive to enhance the interface affinity between BiVO and MIL-101-NH. Due to the highly efficient light capture and sufficient electron traps induced by oxygen vacancies and the formation of a heterostructure, the improved separation and transportation rates of charge carriers are realized. In addition, the MIL-101-NH/BiVO composite is favorable for Cr(VI) photocatalytic removal (91.2%). Moreover, FNBV-3 (Fe/Bi = 0.25) also exhibited an excellent reusability after five cycles.
在这项研究中，通过一种简便且无表面活性剂的方法合成了一种花状的 BiVO/MIL-101-NH 复合材料。-COO-Bi 离子键的构建有助于增强 BiVO 和 MIL-101-NH 之间的界面亲和力。由于氧空位诱导的高效光捕获和充足的电子陷阱以及异质结构的形成，实现了载流子分离和输运速率的提高。此外，MIL-101-NH/BiVO 复合材料有利于 Cr(VI)的光催化去除（91.2%）。此外，Fe/Bi=0.25 的 FNBV-3 在经过五个循环后也表现出了优异的可重复使用性。
