his study describes the CO
2
photoreduction over porphyrin-based metal-organic framework (Co/PMOF) in
the presence of triethanolamine (TEOA) as a photocatalyst and sacrificial agent, respectively, under visible
light irradiation. The photoluminescence properties of porphyrin and Co/PMOF showed that the lifetime of
photogenerated charge carriers in Co/PMOF is longer than porphyrin. According to Fig. 1, Co/PMOF demonstrates
significant photocatalytic activity toward CO
2
reduction. The HCOO¯was continuously produced, the amount
increasing to 23.21 μmol in 6 h. No other products have been detected in gas and liquid phases, suggesting that the
Co/PMOF has highly selective toward the CO
2
reduction. For comparison, TCCP was applied as a photocatalyst for
CO
2
reduction under similar condition. Only 4.56 μmol of HCOO¯ was produced after 6 h which is confirmed the
photoactivity can be significantly increased by assembling the TCPP ligand onto MOFs structure.
