“… The above results indicate that NiFe-CP@Nickel foam obtained with the proposed method has excellent OER catalytic activity, which is comparable with the state-of-the-art coordination polymer-based catalysts but only needs such a simple operation (Figure d and Table S1). , In particular, the preparation efficiency could be a huge leap for the practical production process than the conventional in situ fabrication methods which are always measured for hours, even days . Overall, this method brings broad prospects in the field of rapid in situ preparation of efficient non-noble metal catalytic electrodes in the field of electrocatalysis.…”

Coordination polymers are among the most favored active materials by researchers due to their broad application prospects. However, most of them are usually difficult to directly process into applicable devices because of their unsatisfied processability. One process of great concern for researchers is the in situ preparation of the coordination polymer on the applicable substrate, especially for the favored network substrates with good mechanical properties and 3D porous structure, which could provide obvious convenience and facilitation in the application process. Herein, we present an ultrafast and scalable thermal current-induced dewetting strategy to obtain uniform coordination polymer film in situ on network substrates, which could enable unprecedented convenience to obtain directly usable coordination polymer composites such as practical catalytic electrodes with excellent electrocatalytic performance. The proposed thermal currentinduced dewetting method provides a highly adaptable and efficient practical production approach to integrate coordination polymer materials with network substrates and also provides new inspiration for understanding and applying the dewetting process on complex 3D network substrates.

“…With catalysis and sensing at the forefront of applications for EC-MOFs, it is critical to evaluate the electrochemical performance of different morphologies of electrochemically synthesized Ni-HHTP with that of bulk Ni-HHTP from solvothermal synthesis (Figure S11 in the Supporting Information). Specifically, we focused on Ni-HHTP-Flower due to its lamellar structure (Figures S11, S12, S13, and S14 in the Supporting Information). ,,− The growth of the circular plates in Ni-HHTP-Disc is dense, with the plates stacked on top of each other, shielding portions of the discs from the electrolyte. In contrast, the free space between the Ni-HHTP-Flower “petals” allows 2D Ni-HHTP to remain highly accessible.…”

Electrically conductive metal−organic frameworks (EC-MOFs) are highly sought-after materials for electrocatalysis and energy storage because of their unique combination of intrinsic porosity and electrical conductivity. However, it is challenging to incorporate these exciting materials into functional devices because of the difficulty in synthesizing the frameworks directly on desired substrates and at a scale suitable for mass distribution with a controlled morphology. Electrosynthesis can provide a means that is both scalable and synthetically controllable by which metal−organic frameworks can be grown directly on targeted substrates for use in electronic devices. In this work, we demonstrate the electrosynthesis of an EC-MOF constructed with nickel and 2,3,6,7,10,11-hexahydroxytriphenylene, namely Ni-HHTP, with distinct disc and flower-like morphologies (Ni-HHTP-Disc and Ni-HHTP-Flower) by varying the ligand concentrations. The electrochemical performance of Ni-HHTP-Flower greatly exceeds that of bulk Ni-HHTP, boasting gravimetric capacitances and electrochemically active surface areas up to 10 times that of the bulk material because of mesoporous features absent in the bulk, showcasing electrosynthesis as a promising method for preparing future EC-MOFbased devices.
