Abstract
Nitrogen-containing ordered mesoporous carbon films were synthesized using m-aminophenol as a single carbon and nitrogen source with triblock copolymer Pluronic F127 as a template. First, an m-aminophenol/F127 composite with an ordered mesostructure was formed on a silicon substrate. Successive infiltration of formaldehyde vapor caused copolymerization of m-aminophenol and formaldehyde thereby growing slowly with its ordered mesostructure. This method can form a self-assembly carbon source and triblock copolymer, which cannot be formed by conventional sol–gel methods due to their rapid polymerization of the carbon source. X-ray diffraction patterns and transmission electron microscope observation suggests that the carbon film is composed of some domains which are randomly oriented. The X-ray photoelectron spectroscopy indicates that the carbon film contains large percentages of pyridinic and graphitic nitrogen atoms. Cyclic voltammograms are nearly rectangular in shape, which is ideal for electrochemical double layer capacitors. Additionally, the carbon film exhibits small and broad peaks, indicating that pseudocapacitive reactions occurred on the interior surface due to doping of the nitrogen atoms into the carbon.
