Resumo

WANG, Hui; JI, Shan; WANG, Wei  e  WANG, Rongfang. Amorphous Pt@PdCu/CNT catalyst for methanol electrooxidation. S.Afr.j.chem. (Online) [online]. 2013, vol.66, pp.00-00. ISSN 1996-840X.

A multi-walled carbon nanotube-supported, Pt decorated nano-sized amorphous PdCu alloy cores (denoted as Pt@PdCu/CNT) catalyst with lower Pt loading is synthesized via a galvanic displacement reaction. The structure is examined using X-ray diffraction (XRD) and transmission electron microscopy (TEM). The electrochemical activity of the Pt@PdCu/CNT catalyst is tested by cyclic voltammogrametry (CV) and compared to that of PtRu/CNT catalysts. The results show that amorphous Pt@PdCu/CNT catalyst exhibits better electro-catalytic performances for methanol oxidation than its crystalline counterpart.

Palavras-chave : Amorphous; decorated structured; Pt@PdCu/CNT; electrocatalyst; methanol oxidation.
