The sorption capacities are superior to those of activated
carbon (, 1 times)46, marshmallow-like macroporous gels (6–14
times)1, graphene/a-FeOOH aerogel (13–27 times)47, micro-porous
polymers (, 33 times)12, and our previously reported PDMS-coated
carbonaceous nanofiber aerogel (40–115 times)25; they are comparable
to those of hybrid foam of graphene/CNT (80–130 times)11 and
CNT sponge (80–180 times)35, but lower than those of ultralight
graphene framework (200–600 times)33 and ultra-flyweight CNT/
graphene hybrid aerogels (215–743 times)38.
