The iridium-incorporated Co3O4 (Ir-Co3O4) catalyst is obtained from binary CoIr-based metal-organic framework precursors via controlled calcination treatment. Structural characterization reveals that in situ incorporation of Ir cations can cause lattice expansion of Co3O4 and regulate its electronic structure, thus in turn favoring electrocatalytic performance improvement. With a lattice expansion-induced strain effect, the Ir-Co3O4 catalyst shows superior performance for both electrocatalytic glycerol-to-formate conversion and the hydrogen evolution reaction.
