Synthesis of the Ru-CoPc@TiO2@SiO2@Fe3O4
nanocomposites 6
The resulting CoPcS immobilized TiO2@SiO2@Fe3O4 nano-
composites were taken in DMF and treated with Ru(bpy)2-
phene-NH2 (0.5 g). The resulting mixture was refluxed in the
dark for 24 h under a nitrogen atmosphere. The resulting
nanocomposite 6 was isolated with an external magnet and
washed with DMF, ethanol until the filtrate became colorless.
Finally the resulting material was dried under vacuum. The
analytical values of 6 were found to be C 4.916%; H 1.696%; N
1.305%. The loading of metal complexes in 6 was estimated by
ICP-AES analysis and weight% of Co and Ru were found to be
1.26% and 1.17% respectively.

Photocatalytic reduction of CO2
Photocatalytic experiment was performed in a 100 mL borosil
cylindrical vessel of 5 cm diameter. Photoirradiation was
carried out under visible light by using 20 watt white cold LED
flood light (Model no.-HP-FL-20W-F-Hope LED Opto-Electric
Co. Ltd, λ > 400 nm). The whole spectrum of LED light was
used for illumination purpose. The intensity of the light at the
middle of vessel was found to be 78 W m−2 as determined
using an intensity meter. The vessel was charged initially with
water (40 mL) and triethylamine (10 mL) and then the solution
was degassed by continuous purging of nitrogen for 15 min.
Then CO2 was bubbled through the solution for at least
30 min to saturate the solution. As synthesized photocatalyst 6
(100 mg) was added to the above solution and the vessel was
closed tightly during the reaction and stirred vigorously to
prevent the sedimentation of the catalyst. Samples were col-
lected after every 2 h intervals with the help of a long needle
and the catalyst was removed using a syringe filter (2 nm
PTFE, 13 mm diameter). Quantitative determination was done
by using gas chromatography FID (Varian CP-3800, having
30 m long Stabilwax® w/Integra-Guard® column) at flow rate
0.5 mL min−1, injector temp., 250 °C, and FID detector temp.,
275 °C. A calibration curve was prepared for quantification and
confirmation of linear response of the GC-FID system,

Blank reactions were conducted to ensure that methanol
production was due to the photo-reduction of CO2, and to
eliminate surrounding interference. One blank reaction was
carried out under visible light without the catalyst, and
another was performed in the dark in the presence of catalyst
under identical experimental conditions. An additional blank
test was vis-illuminated with the catalyst filling N2 rather than
CO2. No product was detected in the above three blank tests.
