Abstract
Pt-supported reduced graphene oxide (Pt/RGO) catalysts were prepared over the RGO sheets with different sizes for methanol oxidation and oxygen reduction reactions in acidic media. The Pt on the smaller RGO presented higher catalytic activities than the Pt on the larger RGO and the commercial Pt/C catalyst.
摘要
在不同尺寸的氧化石墨烯（RGO）片上制备了用于酸性介质中甲醇氧化和氧还原反应的铂负载型还原氧化石墨烯（Pt/RGO）催化剂。较小RGO上的铂比更大RGO上的铂以及商业Pt/C催化剂具有更高的催化活性。
