Abstract:
As
the
world
transitions
towards
new
types
of
energy
resources,
the
importance
of
large-scale
hydrogen
production
is
becoming
apparent.
Hydrogen
production
by
electrolysis
would
be
a
perfect
solution
in
near
future,
but
the
efficiency
of
such
a
process
remains
low.
One
of
the
main
reasons
of
the
low
efficiency
is
the
produced
bubbles
not
lifting
off
the
electrode
surface
on
a
timely
manner,
blocking
the
subsequent
production
and
lowering
the
efficiency.
In
this
presentation,
I
will
discuss
explored
possibilities
of
improving
the
aqueous
wettability
of
the
electrode
surface
which
will
force
the
bubbles
to
'lift
off'.
Firstly,
I
will
show
how
a
droplet
on
a
surface
can
be
manipulated
with
specific
ions
and
surfactants.
Subsequently,
I
will
discuss
how
adding
an
electric
field
to
the
chemical
driving
of
droplet
might
or
might
not
a
great
solution.
I
will
wrap
up
by
providing
an
outlook
of
how
the
fundamental
research
of
(electro)chemical
driving
of
droplets
can
lead
to
efficient
and
much
needed
electrodes
in
future.
