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.

However, especially when applying SWATH acquisition for large-scale analysis, e.g. clinical studies with over 1000 s to 10,000 s of samples, simultaneous processing of acquired data in multiple batches over longer period of time may be challenging due to retention time and mass shifts as well as huge bulk of data, particularly when computer power is limited. This problem can be alleviated by a batchwise data processing strategy by inter-batch feature alignment of separately processed sample batches. After batchwise automated data processing in MS-DIAL, feature lists can be combined by aligning identical features from different batches attributed to similarity in precursor m/z and retention time, with the intention to generate a representative reference peak list for targeted data extraction.

The as-prepared NiCoFe-LDH exhibits outstanding electrocatalytic performance under alkaline conditions, achieving low overpotentials of 79.60 ± 0.50 mV for the hydrogen evolution reaction (HER) and 373.40 ± 0.50 mV for the oxygen evolution reaction (OER) at 10 mA cm^-2, along with Tafel slopes of 149.61 ± 0.50 and 77.84 ± 0.50 mV dec^-1, respectively.
