Nitrogen-doped hollow carbon spheres (N-HCSs) were successfully fabricated using silica sphere as template and resorcinol-formaldehyde resin as carbon precursor. Scanning electron microscopy and transmission electron microscopy demonstrated that diameters and shell thickness of N-HCSs were 325 and 25 nm, respectively. The N-HCS modified gold electrode was used for the square wave anodic stripping...
A novel emulsion polymerization–carbonization method was developed to prepare high-temperature-stable (850°C) gold nanoparticle-doped carbon foams using phenolic resins as a carbon source and HAuCl4 as a gold source and acidic catalyst. As-prepared Au–CFs were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD), N2 adsorption and...
