    Abstract

    In this study, the liquid phase reduction technique was used on nanographene oxide sheets (<100 nm), followed by vapor phase reduction of the Pt complex, and we obtained precisely size-controlled Pt nanoclusters with a narrow size distribution on the nanographene sheets with a relatively large surface area. The average sizes of Pt nanocluster were controlled from 1.1 to 2.4 nm by varying initial concentration of Pt complex. Moreover, the Pt sub-nano/nanoclusters mainly attached to the edge of the nanographene sheets and showed superior catalytic performance for electrochemical methanol oxidation.
