High selective photocatalytic CO2 conversion into liquid solar fuel over a cobalt porphyrin-based metal–organic framework

In the present study, porphyrin-based metal–organic framework (Co/PMOF) was synthesized and characterized by different spectra analyses. The photoluminescence properties of porphyrin Co/PMOF revealed that quenched compared to porphyrin, indicating lifetime photo-generated charge carriers in is longer than porphyrin. prepared applied as an efficient photocatalyst for CO2 photoconversion formate presence triethanolamine (TEOA) a sacrificial agent under visible-light irradiation. photoreaction results showed 23.21 µmol HCOO− produced over during 6 h photocatalytic reaction visible illumination, showing much better activity 4.56 HCOO−. No other products were detected, suggesting this has high selectivity. reusability stability examined through recycling tests there no remarkable losses photoactivity even after three cycles photoreaction. Moreover, FTIR measurement UV–Vis demonstrated notable changes structure. As result, superior behavior implied photoreduction which highlights great potential assembly cobalt into MOFs photoreduction.
