Nitrogen-doped Graphitic Porous Carbon

CAS-No. : 7440-44-0

Rapidly advancing technology has created a need to develop energy storage devices that have the power to efficiently store and supply increasingly high levels of energy. The incorporation of highly electronegative nitrogen into carbon frameworks—known as nitrogen doping—serves to increase the positive charge density of the carbon. This increased positive charge density has a number of positive effects, including extra pseudocapacitance and enhanced surface wettability, surface polarity, and electrical conductivity. In addition, the highly porous structure and large surface area of nitrogen-doped graphitic porous carbon in an electrode facilitates increased access of electrolyte ions and provides copious sites for charge adsorption. Thus, supercapacitors with n-doped electrode materials have exceptional long-term cycling stability, a rapid discharge process, and high specific capacitance.

Nitrogen-doped graphitic porous carbon from ACS Material is prepared via high-temperature calcination using ZIF-8 as the template and is acid washed to remove the zinc component. In addition to its applications with supercapacitors, n-doped graphitic porous carbon provides the possibility for exciting innovation in other applications, such as photocatalytic hydrogen evolution, pollutant degradation, and CO2 reduction.
