摘要：

Triphasic nanocrystalline porous material based Fe-x-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. Mossbauer spectroscopy and XPS analyses indicate that Fe-III is the main iron oxidation state present in the films.
