α-Fe 2 O 3 as a photocatalytic material: A review

Electrodeposited Ti-doped hematite photoanodes and their employment for photoelectrocatalytic hydrogen production in the presence of ethanol

“…Hematite (a-Fe 2 O 3 ) is one of the most popular oxide semiconductors and has been used to construct photoanodes for photoelectrochemical water splitting applications [1][2][3][4][5]. Its popularity stems from its visible light absorption, its relatively good efficiency and from the easiness of its synthesis and application on electrodes.…”

Synthetic Formation of Iron Oxides

“…Over the past decade, iron oxides have continued to be central to nanoscience and nanotechnology development. We can take hematite as an example for water-splitting [4] and catalysis application [5], nanomaghemite in nanomedicine and diagnosis [6], or in environment as cheap water cleaner [7]. New methodologies for synthesis that have emerged from these dynamic and considerable advances have been made regarding their colloidal stability and reactivity.…”

Grafted semiconductors on PE-films leading to bacterial inactivation: Synthesis, characterization and mechanism

“…The intervention of FeOx injecting e − into TiO 2 is suggested in Eqs. (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13):…”

“…The deposition of oxides on thermally resistant surfaces reported until now required temperatures of few hundred degrees necessary to anneal the oxides on the support [10,18]. A procedure is also presented to graft the selected oxides on PE at temperatures within the thermal resistance of PE (<96 • C), b) the evaluation o;1;f the E. coli inactivation kinetics on the FeOxTiO 2 -coated films c) a mechanistic outline for the photoinduced charge from FeOx to TiO 2 , based on X-ray photo-electron spectroscopy (XPS) providing a proof for the redox process taking place during bacterial inactivation and d) the film properties characterized by several complementary techniques such as: X-ray fluorescence (XRF), diffuse reflection spectroscopy (DRS), contact angle (CA), surface potential changes and X-ray photoelectron spectroscopy (XPS).…”

“…A method to increase the visible light absorption is to couple TiO 2 with narrow band-gap iron-oxide(s) semiconductor [8,9]. Fe-oxides have also been used as TiO 2 dopants due to its small band gap (∼2.2 eV) for ␣-Fe 2 O 3 , low cost and non-toxicity [10,11].…”
