Can sulfur-modified iron oxides be used as electroactive material for iron–air batteries?
In line with this work, we propose the use of sulfur-modified iron oxides as electroactive material for iron–air batteries. Sulfur-doped or S-modified iron oxides based on hematite have been widely used as Fenton catalysts, since hematite is easily doped with heteroatoms.
Are iron-based rechargeable batteries good for energy storage?
(American Chemical Society) Iron-based rechargeable batteries, because of their low cost, eco-friendliness, and durability, are extremely attractive for large-scale energy storage. A principal challenge in the deployment of these batteries is their relatively low elec. efficiency.
Does sulfur prevent passivation of iron electrodes?
According to several studies, (14,51,52) sulfur prevents passivation of iron electrodes when present as iron sulfide or bismuth sulfide. Some new studies have shown that adding elemental sulfur to the electrodes can have a strong impact in preventing passivation.
Are sulfur-modified mesoporous iron oxides a suitable electrode for alkaline iron–air batteries?
In the present work these two issues are addressed: Sulfur-modified mesoporous iron oxides are obtained and used as hot-pressed negative electrodes for alkaline iron–air batteries. Iron electrodes present average capacity values between 400 and 500 mA h g Fe–1 for ∼100 h of operation, the S-modified iron oxides being the most stable ones.
How are sulfur-modified iron oxides synthesized?
Porous sulfur-modified iron oxides were synthesized following the method presented by Du et al. (23) Oxalic acid dihydrate (C 2 H 2 O 4 ·2H 2 O, 0.04 mol) was dissolved in 100 mL of deionized (DI) water and heated up to 50 °C under vigorous stirring.
Why do iron air batteries need a proper distribution of H2 -inhibiting elements?
During the charging cycle of iron–air batteries (or in general in aqueous electrochemical devices dealing with HER), hydrogen is formed on the surface of the iron particles; therefore it is highly desirable to obtain an iron electroactive material with a proper distribution of the H 2 -inhibiting elements.
