In this work, a metal-organic framework (MOF) material of NH-MIL88B was hybridized with TpPa-1-COF through covalent bonding, and the hybrid was subsequently employed for the degradation of Rhodamine B (RhB) and tetracycline (TC) by simulated sunlight-induced Fenton-like exciting HO. The obtained results show that its photocatalytic activity is much better than those of its parent MOF and covalent organic framework (COF). Moreover, it is much higher than that of bare photocatalysis without Fenton-like excitation of HO. The high degradation efficiency is ascribed to two factors. One is the formation of hybrid, which promotes charge separation and light absorbance. Another is the Fenton-like excitation of HO, which produces more hydroxyl radicals (OH). This report presents a facile approach to greatly improve the photocatalytic property of MOF materials by the formation of hybrid with COFs and Fenton-like excitation of HO.
在这项工作中，通过共价键将金属-有机骨架（MOF）材料 NH-MIL88B 与 TpPa-1-COF 进行杂交，然后将该杂化物用于模拟太阳光诱导的 Fenton 类似激发 HO 降解罗丹明 B（RhB）和四环素（TC）。所得结果表明，其光催化活性远优于其母体 MOF 和共价有机骨架（COF）。此外，它比没有 Fenton 类似激发 HO 的光催化高得多。高降解效率归因于两个因素。一是杂化的形成，促进了电荷分离和光吸收。另一个是 HO 的 Fenton 类似激发，产生了更多的羟基自由基（OH）。本报告提出了一种简便的方法，通过与 COFs 形成杂化物和 Fenton 类似激发 HO，极大地提高了 MOF 材料的光催化性能。
