To increase the robustness of our [Co(dmgH)2pyCl]-based photocatalytic system and to endow recyclability, we sought to create a heterogeneous version of our photocatalytic system by using a cobaloxime as the linker in a MOF. Following previously employed strategies, we synthesized a polytopic cobaloxime linker ([Co(dcpgH)(dcpgH2)Cl2], dcpgH = 4,4′-(1,2bis(hydroxyimino)ethane-1,2-diyl)dibenzoic acid) with four carboxylate anchors for binding to hexazirconium(IV) nodes, which yielded ZrCo-MOF. The PXRD pattern of the obtained material shows intense peaks in the low angle range, characteristic of porous materials (Figure and Figure ). The two major reflections at ∼4.5° and ∼9° indicated a long-range order along the caxis, and this is consistent with the reported partially collapsed framework structure obtained after DMF solvent removal. The partially collapsed structure is also supported by SEM imaging, which shows spherical particles (Figure ). EDX elemental mapping of ZrCo-MOF shows uniform distribution of cobalt and zirconium throughout the material (Figure -h and Figure ). HRTEM images of ZrCo-MOF show lattice fringes that correspond to the (001) planes (d001 = 18.3 Å) (Figure ). The ATR-IR spectrum of the MOF shows Zr-μ3-O stretches at 640 cm -1 that originate from the Zr6 nodes (Figure ). The calculated Brunauer-Emmett-Teller surface area of ZrCo-MOF is 827 m 2 g -1 with a pore size distribution in the range of 9-15 Å (Figure ). The XPS spectrum of ZrCo-MOF is nearly identical to that of [Co(dmgH)2pyCl],
