Efficient electrocatalytic oxygen reduction reaction of thermally optimized carbon black supported zeolitic imidazolate framework nanocrystals under low-temperature

Abstract

Co@CoOx nanoparticle decorated nitrogen-doped carbon derived from zeolitic-imidazolate framework (ZIF-67)@Ketjenblack under mild thermolysis condition delivered impressive ORR activity (Eonset = ∼0.90 V; E1/2 = ∼0.83 V) in alkaline electrolyte.
