Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT A facile coprecipitation‐pyrolysis strategy was employed to fabricate Cu/Co nanoparticles (NPs) embedded in nitrogen‐doped carbon matrices (Cu/Co@N‐C) through the carbonization of CuCo‐MOF precursors. Moreover, monometallic counterparts of Cu@N‐C and Co@N‐C were also prepared via carbonization of bimetallic CuZn‐MOF and CoZn‐MOF, respectively.
