also exhibited no significant difference in CO evolution
(Figure S16). Judging from these control experiments to-
gether with DLS measurements, we concluded that 1 clearly
catalyzes CO2 reduction to CO in a homogeneous manner.

The electrochemical and kinetic data, together with refer-
ence experiments, also lend credence to the proposed mech-
anism of the CO2 reduction by 1 as shown in Scheme 1.
Complex 1 ([NiIIL]2+) is reduced to form [Ni0L]0, which
subsequently reacts with CO2 to afford the intermediate,
[NiL–CO2]0. The intermediate finally releases CO through
the reaction of the CO2 ligand with H2O accompanying the
O-H bond cleavage, and returns to [NiIIL]2+. The RDS of
CO2 reduction by 1 is the CO2 coordination to the reduced
[Ni0L]0 intermediate, although further characterization is
required to investigate the intermediates derived from 1.

In summary, we have developed an efficient photocatalytic
CO2 reduction system using 1, bearing a S2N2-type ligand
inspired by the CODH enzyme as a homogeneous catalyst,
to produce CO selectively in the presence of [Ru(bpy)3]2+ as
a photosensitizer and BIH as an electron donor. The TON
and QY reached to 713 and 1.42%, respectively, which are
the highest values among reported Ni complexes in the pho-
tocatalytic CO2 reduction systems using [Ru(bpy)3]2+. Based
on electrochemical and kinetic results, the RDS of CO2 re-
duction can be the step of CO2 binding to the [Ni0L]0 spe-
cies. Finally, this work has expanded the possibility of ligand
design for the development of efficient and selective photo-
catalytic CO2 reduction using metal-complex catalysts.
