A novel mixed linker Metal-organic Framework, [Co(NHIsoBDC)(bpfn)].DMF (TMU-69), with amide and amino functionalized spacers (bpfn = N,N'-(naphthalene-1,5-diyl)diisonicotinamide, NHIsoBDCH = 5-Aminoisophthalic acid) was synthesized through both solvothermal and ultrasonic approaches. Applying sonochemical irradiation led to ultrafast formation of Flower-shaped nanoplates of TMU-69 within 15 min with high yield while, solvothermal method takes 3 days to form the framework. Control of size and morphology was also enhanced through applying ultrasonic irradiations. The implication of applied time and concentration of reagents on size and morphology of nano-structured TMU-69 have been optimized. Applying higher concentration of initial material with optimized 60-minute irradiation forms uniform smaller sized nanoplates of TMU-69. Also, the efficiency of TMU-69 bulk and nanoplates toward removal of pollutant dyes from water was investigated. The selective adsorption of Congo Red was observed among other dyes. Also, drastic enhancement in removal kinetic of Congo Red through using ultrasonic assisted nanoplates of TMU-69 was obtained.
一种新型混合配体金属有机骨架，[Co(NHIsoBDC)(bpfn)].DMF（TMU-69），具有酰胺和氨基官能化间隔基（bpfn=N,N'-(萘-1,5-二基)二异烟酰胺，NHIsoBDCH=5-氨基异酞酸），通过溶剂热和超声两种方法合成。应用超声化学辐射可在 15 分钟内以高产率快速形成 TMU-69 的花形纳米板，而溶剂热法需要 3 天才能形成骨架。通过施加超声辐射，还增强了对尺寸和形态的控制。优化了施加时间和试剂浓度对纳米结构 TMU-69 的尺寸和形态的影响。施加较高浓度的初始材料并优化 60 分钟的辐射时间可形成均匀的 TMU-69 纳米板。还研究了 TMU-69 块状和纳米板对水中污染物染料的去除效率。在其他染料中观察到对刚果红的选择性吸附。还通过使用超声辅助的 TMU-69 纳米板获得了对刚果红去除动力学的显著增强。
