Author is Mohamed, Eman A.; Zahran, Zaki N.; Naruta, Yoshinori.

For developing renewable fuels and controlling global warming, catalyst promoted conversion of CO2 to CO is essential. Numerous CO2 to CO conversion mol. catalysts have shown very high activity and stability. For large-scale conversion, immobilization of the mol. catalysts to conducting electrodes is essential. Several efficient mol. catalysts have been immobilized to conducting electrodes via phys. bonds. We found that immobilization of a monolayer of the highly efficient Fe porphyrin dimer mol. catalyst via a phosphonic acid anchor to a fluorine-doped tin oxide electrode, FTO/Fe2DTPFPP-PO3H2 showed high activity and stability for CO2 to CO conversion at a very low catalyst loading in nonaqueous and aqueous solutions A high c.d. was achieved for the CO2 to CO conversion by loading more amount of the catalyst to a thin mesoporous layer of SnO2 or TiO2 nanoparticles on FTO. In neutral aqueous solutions, the noninnocent behavior of the FTO electrode was overcome by modifying its catalyst-free surface with hydrophobic Bu phosphonic acid groups.
