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.
