<div><div><div><p>Electrocatalysts for CO2 reduction based on first row transition metal ions have attracted attention as abundant and affordable candidates for energy conversion applications. We hypothesized that a successful strategy in ruthenium electrocatalyst design, featuring two chelating ligands that can be individually tuned to adjust the overpotential and catalytic activity, could be equally applicable in the analogous iron complexes. New iron complexes supported by a redox-active 2,2':6',2''-terpyridine (tpy) ligand and strong trans effect pyridyl- N-heterocyclic carbene ligand (1-methyl-benzimidazol-2-ylidene-3-(2-pyridine)) were synthesized, and these isostructural analogues to leading ruthenium catalysts were also found to be active CO2 reduction electrocatalysts. Electrochemical and computational studies reveal completely distinct mechanisms for the iron and ruthenium complexes, with hemilability in the iron system enabling electrocatalysis at overpotentials as low as 150 mV (ca. 500 mV lower than the ruthenium analogue). Cyclic voltammetry studies elucidated the mechanism of the net 4e–/2H+ process that occurs within the single reductive feature, with an iron solvento complex undergoing reduction, CO2 activation, and further reduction to an iron carbonyl. The mechanistic insight guided development of photoelectrocatalytic conditions under a continuous flow of CO2 that exhibited improved performance, with Faradaic efficiency up to 99%.</p></div></div></div>

Prevention And Therapy

Preparations based on different compounds of bi- and trivalent iron are curently used for the prevention and therapy of sideropenic anemia in human and veterinary medicine. The application of preparations based on dextran started about 1950. Up to now, synthesis and production of preparations were performed with the purpose of improving pharmacological performance by using dextran oligosaccharides with different weight - average molar masses and their oxidized and hydrogenated derivatives. Synthesis of polynuclear iron(lll) complexs with other oligosaccharides (inulin and pullulan) and their derivatives was developed, with potential or valid pharmacological activity for sideropenic anemia treatment.A Review of iron(lll) complexes with different oligosaccharides, their physico-chemical characterization pharmaco-biological performance, global structure, further research and possible applications of then complexes, are presented in this paper.
