However, conventional single-mode electric fields (AC or DC) exhibit inherent \"orientation-distribution\" contradiction. Specifically, AC fields are effective for orientation but lack spatial control, while DC fields promote filler enrichment but fail to optimize orientation state. This study presents an innovative approach by establishing a theoretical framework that integrates both AC and DC electric fields along with a corresponding microscale dynamic model. This approach enables the precise and flexible manipulation of complex filler arrangements, thereby expanding opportunities for advanced material design. The model refines classical dielectrophoresis theory, incorporating interfacial charge and local electric field effects, elucidating the dynamic mechanisms of fillers under combined AC-DC electric fields. Numerical simulations reveal that AC fields primarily control orientation through dielectrophoresis, while DC fields regulate spatial distribution via electrophoresis. The synergistic combination of these two electric fields yields a pronounced \"orientation-enrichment\" effect, enabling the controlled and orderly arrangement of fillers within targeted areas. Moreover, high-aspect-ratio fillers promote chain formation but restrict rotation and migration, and frequencies above 1 kHz suppress alignment and interparticle attraction. Preliminary material design and preparation for enhanced electrical properties of renewable energy transmission device further indicate that this method is effective and flexible for complex application scenarios.

Here, we propose a linker engineering strategy to optimize the phase composition of ultrathin Ni-MOF nanosheet arrays, aiming to enhance both activity and stability. We found that partial substitution of terephthalic acid (BDC) with electron-withdrawing tetrafluoroterephthalate (TFBDC) ligand alters the electronic structure and significantly promotes the formation of the catalytically active γ-NiOOH phase in Ni-TFBDC-2. This results in a 90 mV reduction in the overpotential for the oxygen evolution reaction at 50 mA cm^-2, surpassing the performance of a state-of-the-art RuO₂ catalyst, and is accompanied by an increased corrosion potential in seawater. Furthermore, the enrichment of the γ-NiOOH phase in Ni-TFBDC-2 effectively suppresses the passivation during urea oxidation reaction (UOR) in a seawater electrolyte, enabling the achievement of an industrially relevant current density of 0.8 A cm^-2. Operando characterizations reveal that Ni-TFBDC-2 undergoes an electrooxidation process to form Ni³⁺ species, which subsequently act as the active catalytic sites for the OER. Additionally, the urea-assisted natural seawater electrolyzer assembled with Ni-TFBDC-2 requires a low voltage of 1.76 V at 400 mA cm^-2 and demonstrates excellent durability over 170 h of continuous operation. This work offers a novel strategy to enrich the catalytically active phase in MOF-based electrocatalysts, aiming to achieve high activity and long-term stability during urea-assisted natural seawater electrolysis.
