摘要
Pt/MgO/CNT hybrid electrocatalysts for ethanol electrooxidation were simply prepared in this paper. The micrograph and elemental compositions of Pt/MgO/CNT catalysts were characterized by scanning electron microscopy and energy-dispersive X-ray spectroscopy, respectively. The electrocatalytic properties of the Pt/MgO/CNT catalyst for ethanol oxidation have been investigated by cyclic voltammetry in 1.0 mol L-1 CH3CH2OH and 1.0 mol L-1 KOH aqueous solution. The effect of the content of MgO on the electrocatalytic activity of the Pt/MgO/CNT catalyst was also investigated. Under the same Pt loading mass and experimental conditions for ethanol oxidation, the Pt/MgO/CNT catalyst shows higher electrocatalytic activity than the Pt/CNT catalyst. Additionally, the Pt/MgO/CNT catalyst possesses a good antipoisoning ability.
