This study presents a novel approach to fabricating magnetic sponge-like composites by melting various types of steel onto three-dimensional (3D) carbonized spongin scaffolds under extreme biomimetic conditions. Spongin, renewable marine biopolymer with high thermal stability, was at 1200 °C form turbostratic graphite matrix capable withstanding the high-temperature process (1450–1600 °C). The interaction between molten vapors and resulted in formation nanostructured iron oxide (primarily hematite) coatings, which impart properties resulting composites. Detailed characterization using SEM-EDX, HRTEM, FT-IR, XRD confirmed homogeneous distribution oxides on within fibrous matrix. Electrochemical measurements further demonstrated electrocatalytic potential composite, particularly sample modified stainless 316L—for hydrogen evolution reaction (HER), offering promising perspectives for green production. work highlights biomimetics create functional, scalable, sustainable materials applications catalysis, environmental remediation, energy technologies.

High-performance, cost-effective metal catalysts for alkaline hydrogen evolution reaction (HER) are crucial advancing energy applications. Iron, while affordable and conductive, suffers from excessive adsorption due to its high d-band center, limiting HER efficiency. This study presents a room-temperature synthesis of copper-iron self-supporting electrodes iron microparticles, where the introduction copper significantly improves water dissociation desorption. The electrode achieves low overpotentials 153 431 mV at 10 300 mA cm-2, respectively, with stable performance over 150 h. Notably, this simple method enables direct post-treatment room temperature produce Cu-Fe composite electrodes, demonstrating strong potential practical Furthermore, strategy modulating iron's catalytic not only optimizes efficiency but also offers valuable theoretical guidance design other high-performance catalysts.
