Emerging trends of pseudobrookite Fe2TiO5 photocatalyst: A versatile material for solar water splitting systems

A chemist's guide to photoelectrode development for water splitting – the importance of molecular precursor design

“…In fact, there is excellent compatibility between bespoke precursor design and the fabrication requirements for many of these next generation materials. Hybrid and complex materials such as Fe 2 TiO 5 , 342 perovskites, 343 and organic polymers 344 are among the alternatives. Additionally, computational studies can be used to predict new materials with a myriad of multi-metal elemental compositions as promising next generation photoelectrodes.…”

An Emerging Trend in the Synthesis of Iron Titanate Photocatalyst Toward Water Splitting

“…The introduction of iron into TiO 2 for example reduces its bandgap from 3.2 eV to a bandgap to � 2.1 eV. [23] In recent times, Centurion et al [24] and Imrich et al [25] reviewed the potential of pseudobrookite Fe 2 TiO 5 for solar water splitting systems. The reviews by Rafique et al, [26] Amika et al, [27] Do et al [28] and Aljar et al [29] focused on TiO 2 -based photocatalysts; less emphasis was made concerning iron titanate for photocatalytic activities.…”

Experimental and computational study on the influence of cobalt substitution on the structural, impedance, electronic, magnetic, and optical properties of pseudobrookite-structured Fe2TiO5

“…19 As described by Centurion et al , various modification procedures such as substrate/morphology modification, doping, and cocatalyst loading 20 are available to enhance the photocatalytic properties of Fe 2 TiO 5 . 14 Another excellent approach involves decorating Cu 5 clusters on a TiO 2 surface to increase the photo-absorption, as demonstrated by Pilar de Lara-Castells et al 21 Doping is defined as the substitution of one or more ions at different lattice sites, and it has been shown to alter the structural, electronic, and magnetic properties flexibly in inorganic semiconductors. Two kinds of doping have been achieved in Fe 2 TiO 5 by researchers.…”

“…However, these oxides (TiO 2 bandgap B3.2 eV; ZnO bandgap B3.7 eV) can absorb only ultraviolet light irradiation. [7][8][9] Pseudobrookite-structured iron titanate (Fe 2 TiO 5 ) is an n-type narrow bandgap semiconductor (bandgap B2.2 eV) which has been considered as an alternative to the above-mentioned oxides, and it has been studied in the recent past for its applications in water-splitting, [10][11][12] ceramic pigments, 13 hydrogen generation, 14 Li-ion battery anodes, 15 humidity sensors, 16 and thermoelectric applications. 17 Fe 2 TiO 5 possesses interesting electric and magnetic properties.…”
