The invention belongs to the technical field of nanometer materials, and specifically relates to a three-dimensional
graphene nanoribbon / carbon nanoribbon bridged
aerogel material, a preparation method and application thereof. According to the invention,
aerogel is prepared by assembling basic structural units formed by bridging the
graphene nanoribbon stripped from the carbon nanoribbon with unstripped carbon nanoribbon and
doping the basic structural units with
heteroatom as needed. The preparation of the
aerogel comprises the following steps: preparing a carboxylic
carbon nanotube solution, wherein a proper amount of a soluble
dopant is added or not added into the solution; then carrying out
hydrothermal treatment so as to obtain uniform hydrogel, placing the hydrogel in an ionic impregnation agent for complete replacement, then carrying out secondary
hydrothermal treatment so as to finish a stripping process; and finally, carrying out
drying and carbonizing so as to obtain the
graphene nanoribbon / carbon nanoribbon bridged structural aerogel. The aerogel can be used as an
anode material of
lithium ion battery, shows high specific capacity and excellent stability and rate performance, and has important research significance and good application prospects.
