The electronic structures of carbon nanocages (CNCs) and nitrogen/phosphorus doped carbon nanocages (N-CNCs/P-CNCs) have been studied by X-ray photoelectron spectroscopy (XPS), X-ray absorption spectroscopy (XAS), X-ray emission spectroscopy (XES) and resonant X-ray emission spectroscopy (RXES). The doping configurations for N/P dopants are identified from the experiments. The results have shown that...
Willow or poplar catkins were carbonized to prepare carbon microtubes (CMTs) due to their natural micro-tubular structure. After carbonization at temperatures of 550–950°C, CMTs with outer and inner diameters of 4–8 and 3–7μm were obtained. In addition to having a large and accessible inner tube, a small amount of nitrogen (∼1.8at.%) and phosphorus (∼0.4at.%) dopants cause CMTs prepared at 750°C to...
Carbon-coated iron nanoparticles with diameters ranging from 5 to 50nm and a few layers of graphitic shells have been synthesized in a mass scale by laser-induction complex heating evaporation. Through the studies on the dissolution behavior of the inner iron cores under the treatments of HCl and HNO 3 acids at different conditions, a practical route with the combined treatments of HNO ...
