【摘要】 <正>与传统的石化燃料相比,直接燃料电池具有无污染、能量密度高、运输方便、启动快速、成本低等优势而逐渐引起了人们的广泛关注[1];现阶段甲醇燃料电池催化剂仍存在电催化活性较低、氧化电位过高、成本昂贵等问题。因此,迫切需要探索一种既能提高催化剂活性,又能降低运行成本的新型催化剂制备方法。本文采用简捷的原位合成法把高度分散的铂(Pt)纳米粒子负载到多壁碳纳米管更多还原

【Abstract】 We utilized a simple method to fabricate Pt/MWNT nanocompostes, and the experimental results demonstrated that the size of the Pt NPs and the coverage density on MWNTs could be tuned easily by changing the reaction temperature and the initial mass ratio of Pt(acac)2 to MWNTs. Electrocatalytic measurements showed that the Pt/MWNTs had excellent catalytic activities in the electrooxidation of methanol and in the oxygen reduction reaction. These Pt/MWNT nanocomposites demonstrate potential applications in fuel cells and biosensors.更多还原
