Three-dimensional porous dendritic Pt films (3D PDPFs) were prepared by cathodic deposition utilizing hydrogen bubble dynamic template at room temperature. The deposition conditions including deposition time, electrolyte and substrate were investigated in detail. The deposited PDPFs were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The prepared 3D PDPFs have high catalytic activity for methanol electrocatalytic oxidation. After adsorption of pyridine, the material has surface-enhanced Raman scattering (SERS) signals, and it exhibits super hydrophobic performance after modifying a single layer of n-dodecanethiol. The present method provides a new simple strategy toward the fabrication of 3D PDPFs with multiform applications.
