Chemical activities of graphitic carbon spheres
Monodispersive carbon spheres with a high percentage of purity have been synthesized using a mixed-valent oxide-catalytic carbonization (MVOCC) process. In this paper, the chemical activities of the carbon spheres are examined by dispersing Pt, CdS and WO, nanoparticles, respectively, on the carbon surfaces from the microstructure information provided by transmission electron microscopy. The sp...
متن کاملGraphitic Structure and Surface Chemical Activity of Nanosize Carbon Spheres
Monodispersed nanosize carbon spheres have recently been synthesized using a mixed-valent oxide-catalytic carbonization (MVOCC) process. In this paper, a high surface porosity of carbon spheres produced by an interaction with WO, is reported. The interaction mechanism is due to the reduction of WO, to W driven by an internal Auger decay process under the stimulation of a high-energy electron be...
متن کاملPlasmon excitations in graphitic carbon spheres
Electron energy loss spectroscopy in a high-resolution transmission electron microscope has recently been used with success to characterize the electronic properties of closed cage nanometer-size graphitic particles. In the plasmon region, the experimental data reveal interesting size-dependent variations, which are not yet fully understood. The difficulties encountered in the interpretation of...
متن کاملPlasmon excitations in graphitic carbon spheres measured by EELS
The determination of the physical properties of individual nanometer-size particles has made rapid progress with the availability of local probe techniques during the past years. Electron energy-loss spectroscopy in a high-resolution transmission electron microscope is one experimental tool that can give insight into the intriguing properties of such small particles. The interpretation of the e...
متن کاملTemplate-free synthesis of porous graphitic carbon nitride/carbon composite spheres for electrocatalytic oxygen reduction reaction.
Porous graphitic carbon nitride/carbon composite spheres were synthesized using melamine and cyanuric acid, and glucose as the carbon nitride and carbon precursor, respectively. The 3D hierarchical composites efficiently catalyzed the oxygen reduction reaction with an onset potential of 0.90 V and a kinetic current density of 23.92 mA cm(-2). These merit their promising applications in fuel cel...
