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.
