| Abstract |
In recent years, carbon hybrid nanostructures have attracted attention because of their characteristics derived from both graphene and carbon nanoparticles (CNs). Combining the structure of graphene with CNs arise their unique properties, large surface area, and good water solubility, which make them are expected to be suitable for various application. Here, we report a facile and efficient approach to fabricate N-doped graphene decorated by CNs (NG-CNs) via electrochemical exfoliation of carbon precursor, such as graphite foils. Through direct nanoparticle nucleation in the presence of NG sheets, an NG-CNs hybrid is developed as a highly efficient electrocatalyst for oxygen reduction reaction (ORR) in alkaline conditions. Electrochemical, transmission electron microscopy, and X-ray structure investigations revealed that the nucleation and growth method for forming all-carbon hybrids results in uniform dispersion of CNs on to the surface of NG. The all-carbon hybrids afforded much greater activity and durability than the physical mixture of NG and CNs. This research was also supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (2016R1D1A1B03930895). |
