Abstract Two-fold interpenetration zinc-based metal-organicframework/grapheneoxide (TMU-16-NH2/GO) nanohybrid materials were synthesized under a green, simple and large-scale sonochemical preparation method at room temperature and atmospheric pressure. The role of concentrations of grapheneoxide on size and morphology of nanostructures TMU-16-NH2/GO hybrid have been studied. The materials were characterized
摘要 采用绿色、简单、大规模的声化学制备方法,在室温和常压下合成了双层互穿锌基金属有机骨架/氧化石墨烯(TMU-16-NH2/GO)纳米杂化材料。已经研究了氧化石墨烯浓度对纳米结构 TMU-16-NH2/GO 混合体的尺寸和形态的作用。通过扫描电子显微镜(SEM)、粉末X射线衍射(PXRD)、傅里叶变换红外(FTIR)光谱和氮吸附对材料进行表征。纯 MOF 和纳米杂化 MOF/GO 复合材料均表现出微孔结构和少量介孔。TMU-16-NH2 显示出具有 H4 滞后回线的 IV 型等温线,而 TMU-16-NH2/GO 的等温线似乎显示出具有 H3 型滞后回线的正常 II 型吸附。

Amino-functionalized zirconium and cerium MOFs: Catalysts for visible light induced aerobic oxidation of benzylic alcohols and microwaves assisted N-Alkylation of amines
(2-amino-1,4-benzenedicarboxylate, BDC-NH2, and 4-aminonaphthalene-2,6-dicarboxylate, NDC-NH2) act as effective non-noble-metal-based heterogeneous catalysts, for both the aerobic photooxidation of benzylic alcohols and for the direct microwaves activation N-alkylation of amines with alcohols. The catalytic performance has been studied considering two different approaches: the effect of NH2 functionalized
在本文中,我们报告混合锆-铈-MOFs 与氨基官能化接头(2-氨基-1,4-苯二羧酸酯、BDC-NH 2和 4-氨基萘-2,6-二羧酸酯、NDC-NH 2)同样有效非贵金属基多相催化剂,用于苯甲醇的有氧光氧化和直接微波活化胺与醇的N-烷基化。已经考虑两种不同的方法研究了催化性能:NH 2官能化接头的影响和承载 Ce III 的影响Zr-MOFs 上的物种。Zr-和ZrCe-MOFs在使用分子氧作为氧化剂将醇类光催化选择性氧化为醛类的过程中产生了高效的可见光驱动光催化剂,该催化剂具有高稳定性和显着的可回收性。这些材料也是微波辅助胺与醇的N-烷基化的有效催化剂,选择性地产生亚胺 (ZrCe-MOF) 或相应的仲胺 (Ce-MOF)。
