carbonization and template removal. The obtained NC-800 displays better ORR activity compared with other NC-700 and NC-900 samples. Our results indicate that the superior ORR activity of NC-800 is mainly......
of carbonizing time during the process of first 6 min., after that the carbonization ratio changes little with the time increase, and the carbonized ratio increases with the increase of the C6H6 pressure......
resins derived monodisperse carbon spheres (RFCS)/Se composites were fabricated by the melting-diffusion method. The RFCS were obtained from initial carbonization of resorcinol-formaldehyde resins... of the aforementioned solution and then dried at 80 °C for 6 h. The carbonization process of RFCS were further conducted under nitrogen atmosphere at 600 °C for 4 h and then cooled to room temperature......
