A modified chemical vapor deposition method to synthesize graphene at 360°C is described. Hexachlorobenzene (HCB) was used as carbon source, and copper foils were used as not only the substrates for graphene deposition but also the catalyst to HCB dechlorination. The possible growth mechanism was investigated using X-ray photoelectron spectroscopy. Enhancement of HCB dechlorination by copper played...
A simple mixture of porous magnesium oxide and commercial molybdenum oxide shows high efficiency for the synthesis of carbon nanotubes through the catalytic decomposition of methane at 900°C. Field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, and transmission electron microscopy (TEM) were used to characterize the products. The results indicate that close-packed multi-walled...
