Investigate the relationship between surface structure of Co3O4 and its electrocatalytic activity for the oxygen reduction reaction.
Controllable synthesis of Co3O4 nanocrystals (nanorods, nanocubes, nano-octahedrons) anchored on graphene sheets.
Characterization of different exposed surface structures ({110}, {100}, {111}) and their effects on catalytic performance.
Catalytically active sites for the oxygen reduction reaction are identified as surface Co²⁺ ions.
These sites correlate with the density of catalytically active sites.
Surface Co³⁺ ions primarily facilitate CO oxidation, underscoring the need for morphological control in catalyst design.
