Improvement of photocatalytic activity of brookite titanium dioxide nanorods by surface modification using chemical etching

open access: yes, 2012
Surface morphology of brookite titanium dioxide (TiO2) nanorods was modified by chemical etching with aqueous hydrogen (H2O2)–ammonia (NH3) or sulfuric acid (H2SO4) solution.

A Study on Doped Heterojunctions in TiO2 Nanotubes: An Efficient Photocatalyst for Solar Water Splitting

open access: yesScientific Reports, 2017
The two important factors that affect sunlight assisted water splitting ability of TiO2 are its charge recombination and large band gap. We report the first demonstration of nitrogen doped triphase (anatase-rutile-brookite) TiO2 nanotubes as sun light ...

Synthesis of Amphiphilic Brookite Nanoparticles with High Photocatalytic Performance for Wide Range of Application

open access: yes, 2016
Brookite TiO2 nanoparticles with amphiphilic properties were successfully synthesized with a water-soluble titanium glycolate complex precursor using an oleate-modified hydrothermal growth process. The ∼20–40 nm TiO2 nanoparticles were highly dispersible

Synthesis of nitrogen doped faceted titanium dioxide in pure brookite phase with enhanced visible light photoactivity

open access: yes, 2016
Brookite titanium dioxide (TiO2) is rarely studied, as compared with anatase and rutile phases TiO2, due to its comparatively lower photoactivity. It has been recently reported that brookite TiO2 with active facets exhibits excellent performance, however,

Preparation, characterizations and photochemical applications of brookite-phase TiO2

open access: yes, 2010
本研究探討四氯化鈦(TiCl4)在高濃度硝酸(5 M HNO3)水溶液系統中,鈦離子濃度([Ti4+])及反應溫度對生成二氧化鈦晶相[銳鈦礦(anatase)、板鈦礦(brookite)及金紅石(rutile)]的影響。結果顯示在100 oC下,在我們所探討的[Ti4+]區間內(0.3 - 0.6M),產物晶相皆為brookite/rutile混相。在70 oC下,當鈦離子濃度為0.3, 0.6及0.8 M時,產物晶相分別為brookite/rutile混相,anatase/brookite ...

A Density Functional Theory Study of CO2 Interaction with Brookite TiO2 [PDF]

open access: yes, 2012
: Over the past years, an interest has arisen in resolving two major issues: increased carbon dioxide (CO2) emissions and depleting energy resources. A convenient solution would be a process that could simultaneously use CO2 while producing energy.
