In
summary,
we
have
summarized
the
literature
results
on
exploring
efficient
photocatalysts
for
artificial
synthesis
of
CO2 and
H2O
in
terms
of
light
harvesting
and
charge
transfer
boosting,
as
well
as
the
mechanism
of
CO2 reduction
including
CO2 adsorp-
tion/activation
and
possible
reaction
pathways
in
correlating
to
the
product
selectivity.
