    直接甲醇燃料电池由于其低毒、高能量密度、环境可持续性、高能量转换效率和结构紧凑等优点受到了大量的关注。然而较低的催化性能和高成本是限制直接甲醇燃料电池商业化应用的主要挑战。因此迫切需要制备出催化活性高、成本较低的催化剂来顺应直接甲醇燃料电池的发展趋势。 为了提高催化剂性能、降低催化剂成本,本文制备了PtRu/C核壳催化剂、双壳层PtRu/TiO2催化剂和H-PtRu催化剂。采用X射线衍射(XRD)、扫描电子显微镜(SEM)、能谱分析(EDX)、透射电子显微镜(TEM)以及X射线光电子能谱(XPS)来研究催化剂的形貌、结构和组分。利用循环伏安法和计时电流法来测试催化剂的甲醇氧化电化学性能。主要...Direct methanol fuel cell (DMFC) has attracted many interests due to its low toxicity, high energy density, environmental sustainability, high energy-conversion efficiency and compact system. However, the insufficient catalytic performance and high cost issues are the main challenges that hinder the commercial application of DMFC. Thus, developing new catalysts to improve the catalytic activity an...学位:工学硕士院系专业:化学化工学院_工程硕士(化学工程)学号:2062013115147
