چکیده مقاله :
This research is motivated to identify newly synthesized MOF nano-catalyst via metal-organic frameworks UiO-66-Type with free carboxylic acid as an efficient MOF functionalized graphitic carbon nitride (g-C3N4) via stabilization of Gold Nanoparticles. In order to prepare a highly efficient catalyst UiO-66-COOH @ g-C3N4 @ Au-NPs as a heterogeneous catalyst for applying in reduction of nitro aromatic compounds which have been investigated. In this process, the design, synthesis and construction of a type of metal-organic framework UiO-66 under the title UiO-66-COOH was investigated [1]. UiO-66 (Zr)-type metal organic framework with free carboxylic acid was synthesized in one step from zirconium chloride (ZrCl4) and 1,2,4-BTC (1,2,4-benzene tricarboxylic acid) [1]. Graphitic carbon nitride (g-C3N4), as a polymeric semiconductor, is promising for some applications because of its suitable electronic structures, together with the low cost, facile preparation, and metal-free feature [2]. Since it exhibits a stacked structure, g-C3N4 is often considered as sp2-hybridized nitrogen-substituted graphene. So, UiO-66-COOH can be functionalized to Au metal nanoparticles using g-C3N4 nitrogen-substituted (Scheme).
