چکیده

Water splitting, as an advanced energy conversion technology, consists of two half-reactions, including oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). However, the ideal electrocatalysts are noble metal-based catalysts. Their high cost and scarcity on earth seriously restrict the large deployments. NiSe-based materials have attracted significant attention due to their excellent catalytic properties for OER and HER. Nevertheless, their conductivity and electrochemical stability at high current density are unsatisfactory, resulting in ineffective water splitting due to high impedance and low stability. Recently, a series of catalysts coating NiSe-based materials on the different substrates such as ۳D nickel foam and carbon cloth and other substrates were extremely stable under the circumstance of high current density.There are several meaningful reviews about the NiSe-based electrocatalysts and the electrocatalysts on ۳D nickel foam, carbon cloth, and other substrates. However, no systematic review about the combination of them for OER and HER has been reported yet. Therefore, in this review, we summarize the reports of NiFe-based catalysts on nickel foam in OER and HER, respectively. This review will provide a more comprehensive understanding of NiFe-based electrocatalysts on ۳D nickel foam, carbon cloth, and other substrates and give some references for the design of such electrocatalysts in the future.

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.
