Whatman® cellulosic filter paper was used as a substrate for the synthesis of two zeolitic imidazolate frameworks (ZIFs); ZIF-8 and ZIF-67 with and without 2,2,6,6-tetramethyl-1-piperidine oxoammonium salt (TEMPO)-oxidized cellulose nanofibril (TOCNF). All synthesis procedures take place at room temperature via a one-pot procedure. The synthesis steps were followed using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transforms infrared (FT-IR). Data indicated the formation of metal oxide that converted to a pure phase of ZIFs after the addition of the organic linker i.e. 2-methyl imidazole (Hmim). The materials were characterized using XRD, FT-IR, SEM, energy dispersive X-ray (EDX), nitrogen adsorption-desorption isotherms, and X-ray photoelectron microscope (XPS). Data analysis confirms the synthesis of ZIFs into Whatman® filter paper. The materials were used for the reduction of pollutants such as 4-nitrophenol (4-NP) compound to 4-aminophenol (4-AP). The materials exhibit high potential for water treatment and may open new exploration for hybrid materials consisting of cellulose and ZIFs.

沸石咪唑酯骨架原位生长成纤维素滤纸以还原 4-硝基苯酚

Whatman® 纤维素滤纸用作合成两种沸石咪唑酯骨架 (ZIF) 的基材;ZIF-8 和 ZIF-67 含和不含 2,2,6,6-四甲基-1-哌啶氧铵盐 (TEMPO)-氧化纤维素纳米原纤维 (TOCNF)。所有合成过程均通过一锅法在室温下进行。使用 X 射线衍射 (XRD)、扫描电子显微镜 (SEM) 和傅里叶变换红外 (FT-IR) 跟踪合成步骤。数据表明金属氧化物的形成,在添加有机连接体即 2-甲基咪唑 (Hmim) 后转化为纯 ZIF 相。使用XRD、FT-IR、SEM、能量色散X射线(EDX)、氮吸附-解吸等温线和X射线光电子显微镜(XPS)对材料进行表征。数据分析证实了 ZIF 合成到 Whatman® 滤纸中。该材料用于将污染物如4-硝基苯酚(4-NP)化合物还原为4-氨基苯酚(4-AP)。这些材料在水处理方面表现出很高的潜力,并可能为由纤维素和 ZIF 组成的混合材料开辟新的探索之路。
