Molten salt electrochemical modulation of Ni/Co nanoparticles onto N-doped carbon for oxygen reduction
文献摘要：
Activation of oxygen over non-precious materials has been an imperative task to develop efficient elec-trochemical energy storage and conversion such as fuel cells and metal-air batteries.Herein,a molten salt electrochemical modulation of metal-nitrogen-carbon based compounds(M-N-C)is achieved.By elec-trochemical treatment of polydopamine-coated NiCo2O4(NiCo2O4@PDA)in molten Li2CO3-Na2CO3-K2CO3 at 500℃,Ni/Co bimetal-nitrogen-carbon catalyst(denoted as Ni/Co@NC)consisting of Ni-Co nanoparticles anchoring on porous nitrogen-doped carbon is constructed and evaluated as electrocata-lysts towards the oxygen reduction reaction(ORR).Experimental and calculation results confirm that alloying of Ni-Co and nitrogen doping to carbon enhances the rate-determining transformation of *OH intermediate during ORR.The Ni/Co@NC hence shows an ORR activity comparable with the commercial Pt/C.
