WebMay 24, 2024 · ical FeFe–PBA can go through a two Naþ insertion in each unit with a theoretical capacity of about 170mAhg 1 based on the formula Na 2FeFe(CN) 6. [19] Among the metal elements like Mn, Co, V, and Ti, Mn2 þ/Mn3 redox couple should be a good candidate to substitute Fe due to its low cost and reversible redox behavior.[20–23] The … WebThe Fe@NC and bimetallic CoFe@NC electrocatalysts were derived from calcining FeFe-PBA and CoFe-PBA precursors at various temperatures under an argon atmosphere. Compared with an Fe@NC electrocatalyst, the bimetallic CoFe@NC electrocatalysts possess better ORR activities and stability under alkaline and neutral conditions.
