直接甲醇燃料电池铂基阳极催化剂碳载体发展 杨民力1 (1.北京有色金属研究总院国家有色金属及电子材料分析测试中心,北京,100088) 摘要:碳载铂基材料是最常用的甲醇电氧化催化剂,而载体对催化剂颗粒的分散,活性以及耐久性有着显著的影响.所述文献中的碳载体材料主要分为7类:Vulcan XC-72,空心碳球,有序介孔碳,纳米纤维,纳米管,纳米角和石墨烯.新型碳载体的高比表面积和适宜的多孔性促进了催化剂组分的分散,有利于改善三相界面和提高铂基金属的利用率.表面改性以及着眼于改善碳腐蚀性能的石墨化和掺杂将被继续地深入研究,石墨烯的探索以及多孔,多层次微观结构载体的发展应被重视. 关键词:铂; 阳极催化剂; 直接甲醇燃料电池; 碳载体; platinum; anode catalyst; direct methanol fuel cell; carbon supports; [全文......
