The poor stability and low catalytic activity of NH2-UiO-66 in basic solutions require the reactions to be conducted in acidic solutions, which seriously hinders its potential photocatalytic application. Herein, we report that NH2-UiO-66 coated with two-dimensional covalent organic frameworks (COFs) via imine bond connection presents not only high photocatalytic activity but also high stability and adaptability to the solution environment. The NH2-UiO-66/COF hybrid material was fabricated through the Schiff base reaction of NH2-UiO-66 with 4,4′,4″-(1,3,5-triazine-2,4,6-triyl)trianiline (TAPT) and 2,4,6-triformylphloroglucinol (TP). The hybrid material showed high stability in an alkaline environment, with only 4.7% of NH2-UiO-66 decomposed after the photocatalytic reaction. The optimum photocatalytic H2 evolution rate was 8.44 mmol·h–1·g–1 when triethanolamine was used as an electron-donating agent. The results presented here illustrate the possibility for effectively improving both the photocatalytic performance and stability of NH2-UiO-66 by coupling with COFs.

NH 2 -UiO-66 包覆二维共价有机骨架：高稳定性和光催化活性
NH 2 -UiO-66在碱性溶液中稳定性差、催化活性低，需要在酸性溶液中进行反应，严重阻碍了其潜在的光催化应用。在此，我们报道了通过亚胺键连接涂覆有二维共价有机骨架 (COF) 的NH 2 -UiO-66 不仅具有高光催化活性，而且具有高稳定性和对溶液环境的适应性。NH 2 -UiO-66/COF杂化材料是通过NH 2 -UiO-66与4,4',4″-(1,3,5-triazine-2,4,6-triyl )三苯胺 (TAPT) 和 2,4,6-三甲酰基间苯三酚 (TP)。该杂化材料在碱性环境中表现出高稳定性，仅含 4.7% 的 NH2 -UiO-66在光催化反应后分解。当以三乙醇胺为给电子剂时，光催化H 2的最佳析出率为8.44 mmol·h –1 ·g –1。此处呈现的结果说明了通过与 COF 偶联有效提高 NH 2 -UiO-66的光催化性能和稳定性的可能性。
