Brookite, a sometimes under evaluated TiO2 polymorph [PDF]

open access: yesRSC Advances, 2022
Brookite positively affects solar photocatalysis, electrocatalysis and electrochemical applications by stabilizing photogenerated e−/h+ pairs. Brookite-related heterojunctions, cus Ti atoms, surface acidity and redox behaviour are crucial aspects.

Synthesis of Pure Brookite Nanorods in a Nonaqueous Growth Environment

open access: yesCrystals, 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 ...

High-fraction brookite films from amorphous precursors [PDF]

open access: yesScientific Reports, 2017
AbstractStructure-specific synthesis processes are of key importance to the growth of polymorphic functional compounds such as TiO2, where material properties strongly depend on structure as well as chemistry. The robust growth of the brookite polymorph of TiO2, a promising photocatalyst, has been difficult in both powder and thin-film forms due to the

Preparation and investigation of the photocatalytic properties of Brookite

open access: yes, 2016
Brookite, anatase, and rutile were hydrothermally synthesized and characterized by XRD, Raman spectroscopy, SEM, N2 sorption, thermal analysis, DR UV-vis spectra. The spherical brookite and anatase nanoparticles are of 10 nm size, while the rod-like rutile crystals are larger (500 nm).

DFT study of TiO2 brookite (210) surface doped with silver and molybdenum

open access: yesMaterials Research Express, 2022
The most popular semiconductor in dye-sensitized solar cells (DSSCs) is titanium dioxide (TiO _2 ) because of its low cost, non-toxicity, and good stability.

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

open access: yesYankuang 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 ...

Reduced grey brookite for noble metal free photocatalytic H2 evolution [PDF]

open access: yes, 2021
Herein we introduce for the first time a reduced "grey"brookite TiO2 photocatalyst, produced by thermal hydrogenation of brookite nanoparticles, that shows a remarkable noble metal free photocatalytic H2 evolution.

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

open access: yesNanomaterials, 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 ...
