How It's Made
Waste pomelo peel undergoes freeze-drying followed by high-temperature carbonization (typically 600-800°C). KOH activation creates hierarchical porous structure. The amount of KOH activator controls pore configuration. Room temperature processing after activation. Low-cost, scalable production from agricultural waste. Nitrogen doping available (YB-K5-N variant).
