Resumo

Renewable energy production from diverse sources (such as solar, wind) is essential for achieving a sus-tainable and CO2-free society within a short duration. Green hydrogen is regarded as the most feasible fuel for the next generation of fuel-cell electric vehicles and associated technologies. Solar water splitting is a promising strategy for green hydrogen production because it is based on renewable sources with the po-tential to minimize the power costs in the production of H2 via electrolysis, which presents significant barriers. Iron titanate (Fe2TiO5), a visible-light-active photocatalyst, has emerged as a possible material for designing the next generation of water splitting photoelectrodes, as it is a low-cost, plentiful, and non-toxic oxide with favorable electronic, optical, and chemical properties for this application. This review sum-marizes recent advances in the use of Fe2TiO5 as a semiconducting material for solar water splitting ap-plications, covering single photocatalytic systems and heterostructures such as Fe2TiO5/TiO2, Fe2TiO5/BiVO4, and Fe2TiO5/Fe2O3. Furthermore, this perspective review discusses and highlights strategies for developing effective Fe2TiO5 based water-oxidation materials.(c) 2022 Elsevier B.V. All rights reserved. (AU)
