Abstract
Rare
earth
vanadates
are
promising
for
solar‐to‐fuel
conversions,
yet
their
photocatalytic
efficiency
is
limited
by
the
substantial
recombination
of
photo‐generated
carriers.
Constructing
heterojunctions
recognized
as
an
effective
approach
to
improving
charge
carrier
separation
in
vanadates.
Nonetheless,
inefficient
transfer
often
results
from
poor
quality
interfaces
and
non‐directional
within
these
heterojunctions.
