Identification of TiO2 Polymorphs of the Bauxite Deposit in Central Guangxi by Laser Raman Spectroscopy

Yankuang ceshi, 2022
BACKGROUND Rutile, anatase and brookite are TiO2 polymorphs. In the rutile in-situ U-Pb dating, rutile was determined primarily on electron microprobe data and cathodoluminescence images, while these methods sometimes could not effectively distinguish ...

Low-Temperature Processed Brookite Interfacial Modification for Perovskite Solar Cells with Improved Performance

Nanomaterials, 2022
The scaffold layer plays an important role in transporting electrons and preventing carrier recombination in mesoporous perovskite solar cells (PSCs), so the engineering of the interface between the scaffold layer and the light absorption layer has ...

Synthesis of Pure Brookite Nanorods in a Nonaqueous Growth Environment

Crystals, 2019
Brookite TiO2 is the most difficult TiO2 polymorph to synthesize. The available methods in the literature to produce brookite nanostructures mostly use water-based techniques for the preparation of water-soluble Ti complexes first, followed by a ...

Comparison on the TiO2 crystalline phases deposited via dip and spin coating using green sol–gel route

Journal of Materials Research and Technology, 2019
TiO2 exist in three polymorphs known as anatase, rutile and brookite. Amongst these polymorphs, brookite are less reported and mostly produced as a by-product.

Synthesis of Brookite Titanium Dioxide Nanorods using Salt-Assisted Ultrasonic Spray Pyrolysis Process and their Photocatalytic Activities [PDF]

Archives of Metallurgy and Materials
Here, We present the first-ever synthetic method based on the salt-assisted ultrasonic spray pyrolysis process of pure brookite TiO2 nanorods. H2TiF6 and NaNO3 were used as a titanium precursor and salt for the synthesis, the NaNO3 contributes to the ...

Ti-Nb Mineralization of Late Carbonatites and Role of Fluids in Its Formation: Petyayan-Vara Rare-Earth Carbonatites (Vuoriyarvi Massif, Russia)

Geosciences, 2018
This article is devoted to the geology of titanium-rich varieties of the Petyayan-Vara rare-earth dolomitic carbonatites in Vuoriyarvi, Northwest Russia. Analogues of these varieties are present in many carbonatite complexes. The aim of this study was to
