چکیده

Metal–organic frameworks are a new class of advanced porous materials, which have several important characteristics, such as highly periodical, diverse and designable structures, high porosity, unique and modifiable pore surface, as well as framework flexibility [1].Metal-organic frameworks (MOFs) are a class of porous crystalline materials composed of organic linkers and inorganic nodes. For the past decade, they have been extensively studied because of their extraordinary porosity that makes them suitable for catalysis, gas separation, sensors, biomedical science, and supercapacitors. In particular, robust MOFs with strong coordination covalent bonds, such as those between metal atoms and carboxylates, are of interest. In this context, Zr-based MOFs, such as UiO-668 (nominal composition: Zr6O4(OH)4(BDC)6; BDC = benzene-1,4-dicarboxylate) featured zirconium oxide cluster (Zr6O8) secondary building unit (SBU) are known for their high mechanical, chemical, and thermal stabilities [2].In this research, ZrCl4 and benzene-1,4-dicarboxylate )BDC( as linker were used in various solvents (Dimethylformamide, ethanol, distilled water) by mechanochemical method. The characterization of the obtained MOF was conducted by XRD, FTIR and SEM.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
