In this study, a cathode material consisting of α‐Fe2O3 nanoseeds and carbon nanotubes (CNT) is presented, which achieves excellent cycling stability on deep (dis)charge with high capacity. The initial capacity of Fe2O3/CNT electrode reaches 805 mA h g?1 (0.7 mA h cm?2) at 0.2 ...
The short diffusion length of photo-excited charge carriers in Fe O is one of the factors limiting the water splitting efficiency of iron oxide based materials. To overcome this problem we are engineering transparent arrays of nanowires to act as conducting substrates for the Fe O . To help un...
The Oxygen Evolution Reaction (OER) is vital for energy conversion and storage. This study presents a multi-heterostructure catalyst, Fe2O3/Co3O4/Co(PO3)2, created by encapsulating Fe ions in COF/MOF pores through grinding and one-step pyrolysis. The cat

Then the extra VO3− around the FeVO4 colloidal particles can react with unstable Fe(OH)3, resulting the phase transformation from α-Fe2O3 (47.99–7.16%) into FeVO4 (52.01–92.84%), promoting photocarriers' generation capacities. After final carbonization, a part of C atoms enter into...

Hematite (α-Fe2O3), with a bandgap suitable for absorption of the solar spectrum, is ideally suited for use as a photoanode material in photoelectrochemical (PEC) conversion of solar light into hydrogen fuel via water splitting. However, low hole mobility, short hole lifetime, high density ...
The optical results showed that the absorbance and visible light activity of Fe2O3 and BiVO4 is significantly improved by WO3 backbone fibers due to high amount of photo absorber loading. In addition, one dimensional (1-D) WO3 fibers beneficially enhance the optical path length to the ...
Large area self-standing nanosheets of mixed iron (III) oxyhydroxide/oxide (lepidocrocite, γ-FeOOH and maghemite, γ-Fe2O3) were grown directly from an iron foil based on a simple chemical oxidation route. The γ-FeOOH and γ-Fe2O3 nanosheets on a conductive substrate can be used ...
Fe4O5that adopts an orthorhombic CaFe3O5-type crystal structure that features linear chains of Fe ions. On cooling below∼150 K, Fe4O5undergoes an unusual charge-ordering transition that involves competing dimeric and trimeric ordering within the chains of Fe ions. This transition is ...
