Resumo |
Gas bubble dynamic template, a new green and promising template, can be used to prepare nanostructured materials with different shapes from electrochemical deposition processes. Different morphological platinum nanomaterials have been synthesized by the replacement reaction of the deposited copper nanomaterials which were obtained under negative potential along with H-2 evolution (dynamic template) at a glassy carbon electrode. Scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and electrochemical methods were adopted to characterize their structures and properties. The nanomaterials platinum exhibited excellent catalytic activity toward oxygen reduction. The results demonstrated that the strategy is a simple, cost-effective, and potent method to prepare platinum nanomaterials. |
