Abstract
Many
cases
of
light
absorption
modification
exceeding
700
nm
or
near‐infrared
(NIR)
are
reported
for
capturing
more
than
half
the
solar
energy,
however,
very
few
modifications
can
produce
NIR
photoactivity
due
to
inevitably
introduced
defects‐induced
non‐radiative
recombination.
Here,
taking
four
kinds
C/O
co‐doped
red
polymeric
carbon
nitride
as
examples,
defect‐repairing
is
carried
out
using
alkali
metal
molten‐salts
(LiCl/NaCl
and
LiCl/KCl)
solid‐salt
(KCl)
activate
their
photoactivity.
The
defect
repair
results
from
passivation
valence
electron
pairing
formation
crystalline
polyheptazine
imide
structure
with
complete
polymerization.
More
importantly,
it
sharply
eliminates
bulk
defects
(such
vacancy
nitrogen
vacancy)
by
co‐doping.
Since
structural
in
most
photocatalysts
during
expanding
absorption,
this
proposed
strategy
bound
be
universal
suppressing
recombination
