高表面活性聚苯胺/纳米碳复合载体载铂催化剂的制备及结构性能研究 ; Fabrication and Characterization of Pt Catalyst on PANI/Nano Carbons Composite Carriers with High Surface Activity
科技与经济的高速发展让能源危机和环境污染问题日益受重视,燃料电池作为“二十一世纪的清洁能源”日益成为关注和研究的焦点。直接甲醇燃料电池(DMFC)以甲醇作为燃料,具有来源丰富、价格便宜、在常温下是液体、易携带和储存且能量密度高等优点,将成为比氢燃料电池更具有吸引力的一类质子交换膜燃料电池(PEMFC)。阳极催化剂是DMFC关键的组成部分。目前铂(Pt)是DMFC体系中最适的催化剂,但利用效率低和CO中毒是主要问题。针对这些问题,本论文通过制备出具有高表面活性的聚苯胺/纳米碳复合材料,以之作为铂金属载体,使金属粒子在载体表面呈均匀的分散状态,提高了Pt催化剂的利用率;Pt粒子与聚苯胺之间存在的协. ; With the rapid development of technology and economy, the energy crisis and environmental problems are received increasing attention. Fuel cell as the "Clean Energy In the 21st Century" is increasingly becoming a concern and research focus. Direct methanol fuel cell (DMFC),using methanol as fuel, being abundant sources, low prices, liquids at room temperature, easy to carry and store and higher en. ; 学位:理学硕士 ; 院系专业:化学化工学院材料科学与工程系_高分子化学与物理 ; 学号:200436005
