Опубликована: Март 20, 2025

Abstract Given the rising global energy demand and increasing emphasis on environmental protection, development of renewable conversion technologies to replace fossil fuels has emerged as a critical research priority. Among these technologies, seawater electrocatalysis garnered attention high‐efficiency environmentally friendly approach. This review summarizes recent advancements in for resource extraction, covering reaction mechanisms hydrogen production via electrolysis progress electrocatalytic materials. Specifically, we discuss materials based non‐precious metals, precious nonmetals, bifunctional electrocatalysts. Additionally, inorganic pollutants (e. g., hydrazine, sulfides) organic compounds urea, microplastics) is reviewed, emphasizing its significance marine utilization remediation. We also explore electrochemical strategies extracting valuable metal ions, such calcium, magnesium, uranium, lithium, abundant seawater. Although faces challenges terms cost technical scalability, technology interdisciplinary collaboration offer promising prospects commercialization with potential make substantial contributions sustainable development.

Abstract Chiral compounds play a pivotal role in pharmaceutical chemistry, and the oxidation of chiral alcohols to corresponding carboxylic acids is crucial step. However, enantioselectivity susceptible degradation due sensitivity enol isomerization racemization. In this study, Ru/S‐Ni‐MOFs electrocatalysts with high specific surface area were synthesized. After undergoing electrochemical reconfiguration, which combined 4‐acetamido‐TEMPO (ACT) as co‐catalysts achieve efficient alcohols, reaching 99% at industrial‐grade current density 500 mA/cm 2 . Additionally, 100 g acid successfully synthesized yield 98% an large‐scale electrolyzer. situ experiments theoretical calculations demonstrated that S doping shifts center d‐band toward Fermi level, stabilizes ACTH inhibits dissociation OH, thereby enhancing electrocatalytic activity. This study presents synergistic strategy for practical electrosynthesis compounds.
