Carbonized biomorphic wood (Bio‐C), which features unique properties such as highly ordered microtexture, well‐developed porous structure, and low charge transfer resistance, was prepared as a promising scaffold with trace amount of platinum (Pt) supported to efficiently electrocatalyze hydrogen evolution reaction (HER). Pt/Bio‐C nanocomposites demonstrated superior HER activity with a current density reaching as high as ∼58 mA cm −2 at −0.2 V vs . reversible hydrogen electrode (RHE) in strongly alkaline condition.
