Structural effects on the oxygen reduction reaction (ORR) on Pt single-crystal electrodes modified with melamine have been investigated. The activity of ORR on Pt(111) modified with melamine was threefold that on bare Pt(111). The ORR activity of Pt(331) = 3(111)-(111), which was the highest among the Pt single-crystal electrodes studied, was increased twofold after the modification with melamine. The ORR activities of other high-index planes (n(111)-(111) series) were also increased after electrode modification with melamine.

三聚氰胺修饰的Pt单晶电极对氧还原反应的结构影响

研究了三聚氰胺修饰的Pt单晶电极对氧还原反应（ORR）的结构影响。ORR对三聚氰胺修饰的Pt（111）的活性是裸Pt（111）的三倍。用三聚氰胺修饰后，Pt（331）= 3（111）-（111）的ORR活性增加了两倍，是研究的Pt单晶电极中最高的。三聚氰胺修饰电极后，其他高折射率平面（n（111）-（111）系列）的ORR活性也增加。
