N-Doped Mesoporous Carbon (NDC05, 600 m2/g) for Supercapacitor and Catalyst Support, 5 g/bottle, CSCSNMC

In supercapacitor technology, Nitrogen-doped Mesoporous Carbon (N-MC) is often considered the "perfected" version of a carbon support. While standard mesoporous carbon provides the high-speed "highways" for ions, adding nitrogen atoms transforms the inert carbon surface into an active participant in charge storage and catalytic reactions.

Nitrogen atoms are typically incorporated into the carbon lattice in four main configurations: Pyridinic-N, Pyrrolic-N, Graphitic-N (Quaternary), and Pyridine-N-oxide. Each plays a specific role: (1) Pseudocapacitance: Pyridinic and pyrrolic nitrogen sites participate in fast, reversible Faradaic (redox) reactions with the electrolyte ions. This can nearly double or triple the specific capacitance compared to undoped carbon. (2) Improved Wettability: Nitrogen is more electronegative than carbon, which increases the surface polarity. This makes the carbon "hydrophilic," allowing the aqueous electrolyte to penetrate deep into the smallest micropores. (3) Enhanced Conductivity: Graphitic nitrogen (quaternary N) donates electrons to the delocalized π-system of the carbon framework, significantly lowering the internal resistance (ESR) and improving the power density.

Notes: Please try to store the N-doped mesoporous carbon powder in a dry place.
