چکیده
One of the newest methods for producing electricity is the microbial fuel cell (MFC), which uses microorganisms to oxidize organic molecules. The low output electrical power level of these cells, which is mostly due to the weak performance of the electrochemical systems used as the cathode, represents one of the key obstacles to their development and potential for widespread usage. The reduction reaction of dissolved oxygen in water (ORR) and its transformation into hydroxide ions at a biological pH close to ۷ is one of the most frequent cathodic reactions in MFCs. This is accomplished using appropriate electrochemical catalysts made of expensive noble metals such as Pt and Pd. These fuel cell efficiencies can be significantly increased if a low-cost, widely accessible, and efficient cathode catalyst is created for the ORR process. Taking intoaccount these issues, in this study, nickel (П) oxide nano-structures were produced on a nickel foam using nickel foam anodizing, and these nano-structures were employed as cathodes in MFC. The results showed that anodized nickel (П) oxide nano-structures lead to a significantly higher power output compared to the bare nickel electrode owing to its higher surface area and nanoscale effects.کلیدواژه 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.
