Abstract:
Graphene
is
recognized
as
one
of
the
nanomaterials
that
could
revolutionize
numerous
industries
over
a
wide
range
of
sectors
due
to
its
distinctive
properties,
including
large
specific
surface
area,
high
electrical
and
thermal
conductivity,
good
chemical
stability,
ultrahigh
mobility,
as
well
as
great
mechanical
strength
and
Young’s
modulus.
The
European
Commission
(EU)
has
recently
committed
1
billion
euros
over
10
years
to
fund
graphene
R&D
through
an
EU
Future
Emerging
Technology
flagship
grant.
The
recent
developments
in
Yu’s
lab
on
production
and
manipulation
of
graphene
will
be
introduced,
in
which
mainly
toward
clean
energy
applications,
such
as
supercapaciors,
batteries
and
hydrogen
production.
Supercapacitors
are
high
power
density
electrochemical
energy
storage
technologies
with
excellent
cyclability,
however
in
order
to
render
them
suitable
for
a
variety
of
applications
including
automotive,
electronics,
grid
scale
energy
storage,
etc.,
advanced
electrode
materials
are
required
that
can
improve
the
energy
density
and
reduce
overall
costs.
A
few
generations
of
graphene
developed
in
Yu’s
group
and
used
as
high
performance
supercapacitor
electodes
which
significanlty
improved
the
capacitance
and
energy
density
of
these
devies.
Yu’s
group
has
also
developed
the
1st
graphene
based,
transparent
and
flexible
supercapacitor
for
wearble/flexible
electronics
in
the
world.
Recently,
advanced
supercapacitor
based
on
three-dimensional
graphene
sponge
based,
consists
of
an
interconnected
network
of
graphene,
have
been
designed
and
dmonstrated
4
time
higher
of
energy
density
than
the
commercial
activated
carbon
supercapacitors.
Other
energy
related
work
in
Yu’s
group
including
photocatalyst
for
H2
production
and
battert
sensor.
