Stable CuO with variable valence states cooperated with active Co2+ as catalyst/co-catalyst for oxygen reduction/methanol oxidation reactions

[Display omitted] •Bimetallic ZIFs-derived Co3O4@NPC@CuO is prepared as ORR catalyst/MOR co-catalyst.•Zn evaporation promotes the exposure of highly-active sites (Co2+) on Co3O4 for ORR.•CuO can effectively transport surface lattice oxygen to enhance ORR activity.•Interaction between Pt and CuO lowe...
