Ultrafastly Interweaving Graphdiyne Nanochain on Arbitrary Substrates and Its Performance as a Supercapacitor Electrode
journal contribution
posted on 2018-03-08, 16:47 authored by Fan Wang, Zicheng Zuo, Hong Shang, Yingjie Zhao, Yuliang LiA moderate
method is first developed here for superfast (in seconds) growth of
an ultrafine graphdiyne (GDY) nanochain on arbitrary substrates in
the atmosphere. This is an environmentally friendly and metal-catalyst-free
method, efficiently eliminating extraneous contaminations for the
carbon materials. The seamless GDY coating on any substrates demonstrates
that an all-carbon GDY possesses outstanding controllability and processability,
perfectly compensating for the drawbacks of prevailing all-carbon
materials. After the decoration of 3D GDY nanostructures, the substrates
become superhydrophobic with contact angles high up to of 148°
and can be used as outstanding frameworks for storing organic pollution.
Because of the reasonable porous and 3D continuous features, the as-prepared
samples can be applied as high-performance binder-free supercapacitor
electrodes with high area capacitance of up to 53.66 mF cm –2, prominent power performance, and robust long-term retention (99%
after 1300 cycles).
