چکیده
Metal–Organic Frameworks (MOFs) attract a lot of attention from the scientist community because of their extremely high porosity and tunable chemical composition. They haveapplications in gas storage, separation, and catalysis[1,2]. Routine synthesis of MOFs involves solvothermal methods, microwave-assisted, mechanochemical, sonochemical and electrochemical synthesis [3,4]. Among these methods, electrochemical synthesis has two mainadvantageous. This method require a few minutes time for synthesis comparing to other methods which require several hours or days for synthesis. Also in electrochemical method usually thesynthesis is accomplished at room temperature. In this work, copper (II) benzene-1,3,5-tricarboxylate (Cu BTC,BTC=1,3,5-tricarboxylate) was synthesized by electrochemical method (Fig. 1) and its performance as electrocatalyst for oxygenreduction reaction (ORR) was studied in 0.5 M H2SO4, phosphate buffer 6 (PBS6) and 0.1 M NaOH solutions, which the best result was obtained in PBS6. At the optimum condition the ORRwas compared with a Cu BTC synthesized by solvothermal method. The ORR results shown that in comparison to solvothermal MOF, the electrosynthesised MOF has very higher current density for ORR, while the overvoltage isکلیدواژه ها

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.
