N-Doped Activated Carbon (NDC03, 1800 m2/g) for Supercapacitor and Catalyst Support, 5 g/bottle, CSCSNAC

In supercapacitor technology, N-doped activated carbon (NAC) is an advanced electrode material that significantly outperforms traditional activated carbon. While standard activated carbon relies almost entirely on the Electrical Double Layer Capacitance (EDLC) mechanism (storing charge via ion adsorption), nitrogen doping introduces a secondary storage mechanism called Pseudocapacitance. 

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 activated carbon powder in a dry place.
