Anion-tuned nickel chalcogenides electrocatalysts for efficient 2e^- ORR towards H₂O₂ production in acidic media.

ABSTRACT: Electrocatalytic 2e^- oxygen reduction reaction (2e^- ORR) is a promising approach to producing H₂O₂ at ambient temperature and pressure especially in acidic media, which, however, is hindered by the high cost of precious metal-based electrocatalysts. Hence, the development of efficient earth-abundant electrocatalysts and reaction mechanism exploration for H₂O₂ production by 2e^- ORR in acidic solution are critically important but remain challenging at present. In this work, NiSe₂ has been developed as a novel and high-performance 2e^- ORR electrocatalyst in acidic media, moreover, using nickel chalcogenides as the models, the influence of different anion species (Se₂^2-, S
