“…It is well-established that in an alkaline environment, the ORR onset potential with iron-based macrocyclic catalysts is dependent on the Fe +3 /Fe +2 redox couple potential. − Hence, the reduction of the metal center is a crucial step in the catalytic reaction. In its initial state, the iron in the complex is at its stable, three-valent state, which is strongly bonded to the hydroxide ions from the solution (Fe 3+ -OH), making it less available to interact with oxygen molecules.…”

The development of precious group metal-free (PGM-free) catalysts for the oxygen reduction reaction is considered as the main thrust for the cost reduction of fuel cell technologies and their mass production. Within the PGM-free category, molecular catalysts offer an advantage over other heattreated PGM-free catalysts owing to their well-defined structure, which enables further design of more active, selective, and durable catalysts. Even though non-heat-treated molecular catalysts with exceptional performance have been reported in the past, they were rarely tested in a fuel cell. Herein, we report on a molecular catalyst under alkaline conditions: fluorinated iron phthalocyanine (FeFPc) supported on cheap and commercially available high-surface area carbonBP2000 (FeFPc@BP2000). It exhibits the highest activity ever reported for molecular catalysts under alkaline conditions in half-cells and fuel cells.

“…This shift to a higher binding energy was also justified as being due to the delocalization of the π electrons, which made iron possess a lower electron density. Similarly, the shift in the binding energy of Fe can also be attributed to columbic interactions between FePc and CNTs [ 37 ].…”

Carbon nanotubes (CNT) were prepared by a modified chemical vapor deposition (CVD) method. The synthesized carbon materials were treated with acidic and basic solutions in order to introduce certain surface functional groups, mainly containing oxygen (OCNT) or amine (ACNT) species. These modified CNTs (OCNT and ACNT) as well as the originally prepared CNT were reacted with a non-ionic Fe complex, Iron (II) Phthalocyanine, and three composites were obtained. The amount of metal complex introduced in each case and the interaction between the complex and the CNT materials were studied with the aid of various characterization techniques such as TGA, XRD, and XPS. The results obtained in these experiments all indicated that the interaction between the complex and the CNT was greatly affected by the functionalization of the latter.

“…The spectra of mesoporous silica-IP showed peaks at 1335, 1530, and 1615 cm −1 corresponding to the phthalocyanine skeleton structure in the iron phthalocyanine micromotor. 28,33 In addition, 891 cm −1 is a characteristic absorption peak of iron ions. 34 The FTIR spectra results show the successful synthesis of mesoporous silica-IP with phthalocyanine framework and iron ions.…”

The detrimental effects of anthropogenic heavy metal pollution on the environment have recently become a pressing concern, with Pb 2+ ions emerging as a particularly hazardous pollutant. In this paper, we report the synthesis and characterization of light-driven mesoporous silica-IP (iron phthalocyanine) nanomaterials that exhibit remarkable efficiency and selectivity in the removal of Pb 2+ ions from wastewater. The fibrous structure of the material provides a large specific surface area and adsorption sites, enabling it to achieve a theoretical maximum adsorption capacity of 69.78 mg/g. In addition, our studies of the adsorption effect of actual wastewater showed a significant reduction in the concentration of Pb 2+ ions to 1.76 mg/L, indicating the excellent effectiveness of the material in treating contaminated water sources. In addition, the photosensitive material on the surface of the material provides reliable light-driving capability, enabling rapid separation of Pb 2+ ions from wastewater with a maximum movement speed of 26 μm/s.
