Phenol-urea-formaldehyde (PUF) organic foam were used as precusors for the new monolithic nitrogen-containing microporous cellular activated carbons production. Carbonization and CO2 activation were used to prepare this novel monolithic nitrogen-containing activated carbon foam with both interconnected macroporous and micro/meso- porosity structures from the developed PUF organic foam.
