First-principles calculations and Raman scattering evidence for local symmetry lowering in rhombohedral ilmenite: Temperature- and pressure-dependent studies
(2018-11-07)
ATiO3-type materials may exist in two different crystalline forms: the perovskite and ilmenite. While many papers have devoted their attention to evaluating the structural properties of the perovskite phase, the structural ...
Degradation of Orange II by Fenton reaction using ilmenite as catalyst
This work deals with the degradation of the
azo-dye Orange II (OII) by a heterogeneous process
with dark Fenton. Natural and purified ilmenites from
Colombian soil were used as catalysts. The catalysts
have different ...

Unveiling the infrared complex dielectric function of ilmenite CdTiO3
(2020-01-15)
This work presents the infrared active modes of the ilmenite phase of CdTiO3. Since the ilmenite phase of cadmium titanate is unstable in large particle size, the dielectric tensor at the infrared region has been extracted ...

Modified ilmenite as catalyst for CWPO-Photoassisted process under LED light
(Elsevier Science Sa, 2017-06)
The influence of the iron chemical nature contained in ilmenite (FeTiO3) upon the activity and stability of these materials as catalysts for CWPO-Photoassisted process under LED light (λ: 405 nm) were evaluated. Raw ilmenite ...
