New Fe2TiO5-based nanoheterostructured mesoporous photoanodes with improved visible light photoresponses

Résumé

Triphasic nanocrystalline porous material based Fex-TiO2 anatase, pseudo-brookite and hematite are generated via a simple templated growth based strategy followed by carefully controlled temperature/atmosphere treatments. As shown by XRD, SEM, and TEM experiments the resulting nano-crystalline mesoporous films exhibit optimized bicontinuous pore-solid architectures and high surface-areas. Mössbauer spectroscopy and XPS analyses indicate that FeIII is the main iron oxidation state present in the films.
