Rationally designed hierarchical macro-/microporous HKUST-1 electrodes were prepared via an electrochemical deposition-dissolution technique with the motivation to overcome diffusion limits that are typically occurring for conventional microporous MOFs. A colloidal crystal of silica spheres was prepared by the Langmuir–Blodgett (LB) technique. Using this crystal as a template, macroporous copper electrodes with a controlled number of pore layers were prepared via electrodeposition. After the removal of the template, the synthesis of HKUST-1 was performed via partial anodic dissolution of the copper surface in the presence of the organic linker, leading to the deposition of the HKUST-1 on the electrode surface with the designed macroporous structure. The macroporous Cu electrodes do not only behave as structural template but are also the Cu source for the formation of MOFs. Applied potential and deposition time allow to fine-tune the characteristics of the porous layer. The developed synthesis is rapid, occurs under mild conditions and therefore opens up various potential applications including catalysis, separation and sensing based on these hierarchical materials.
