Co3O4 nanobelts with predominantly {011} planes exposed are more active for CO oxidation than Co3O4 nanocubes with exposed {001} planes. The shape and crystal plane effects are highlighted by the fact that the turnover frequency (TOF) of Co3+ sites on {011} planes of Co3O4 nanobelts is far higher than that of Co3+ sites on {001} planes of Co3O4 nanocubes.
