摘要
燃料电池是一种环境友好且具有广阔应用前景的绿色电源。燃料电池——直接甲醇燃料电池(DMFC)最重要的障碍之一是使用存储少价格高的铂作为阳极或阴极催化剂。研究者意识到催化剂颗粒和载体材料之间的相互作用对催化性能的影响需要仔细地加以研究。本文不仅对2010年以来DMFC阳极催化剂的发展进行了总结,还关注于纳米催化剂粒径、催化剂制备方法以及二者之间相互作用对电极性能的影响。理解催化剂粒径和载体作用的最终目标是开发出更具成本效益和强大的燃料电池的电催化剂。
Fuel cells are promising green power sources with environmentally benign and broad applications. One of the most important impediments for fuel cells such as direct methanol fuel cells（DMFCs） is to mainly use the precious and rare reserve Pt as an anode or cathode electrocatalyst. Researchers recognize that the effects of the interaction between catalyst particles and supporting materials on catalytic performance need carefully consideration. This article not only presents a review of the development of anode catalysis for DMF- Cs since 2010 but also focuses on effects of nanocatalyst particle size, catalyst preparation methods, and strong interaction between cata- lysts and controlling synthetic procedures and conditions. The ultimate goal was to acquire a better understanding amenable to particle size and support effects in electrocatalysis, drive the advancement of more effective and perfect catalysts in the future.
