TLDR
In this paper, the industrial and laboratory synthesis, molecular structure and reactivity of titanium(IV) carboxylate complexes stable in aqueous medium are presented. And a special accent is made on the solution ligand-transfer equilibria that are able to provide uniform TiO2 nanoparticles under rather mild conditions starting from these easily commercially available species.Abstract:
The review presents the industrial and laboratory synthesis, molecular structure and reactivity of titanium(IV) carboxylate complexes stable in aqueous medium. A special accent is made on the solution ligand-transfer equilibria that are able to provide uniform TiO2 nanoparticles under rather mild conditions starting from these easily commercially available species. Application of titanium oxide nanostructures derived from solution-generated titania nanoparticles is described in detail.read more

TL;DR: This work describes tailoring the crystallinity of metal oxide precursors that enable the formation of highly ordered, large-area (mm2 ) crack-free titania, zirconia, and alumina IO films and how this bioinspired approach can be applied to other crystalline materials as well as structures beyond IOs.

Controlled synthesis of titania using water-soluble titanium complexes: A review
TL;DR: In this article, the progress of synthesis of nanocrystalline titanium dioxide using water-soluble titanium complexes (WSTC) is reviewed in this work and the key structural features responsible for the successfully controlled synthesis of TiO2 are discussed to provide guidelines for the morphology-controlled synthesis.

A preferential precursor for photocatalytically active titanium dioxide thin films: Titanium bis-ammonium lactato dihydroxide as an alternative to titanium tetra iso-propoxide
TL;DR: In this article, a comparison of the photocatalytic performance of the two precursors for sol-gel deposition of TiO2 thin films is given, including a discussion into the proposed differing decomposition mechanisms that may occur during solgel preparation, and the morphology and nanostructure of the films have been assessed using SEM, XRD and Raman spectroscopy.

TL;DR: It has been determined that the increase in the amount of the condensed Q(4) silica in the mixed oxides leads to the decrease in photocatalytic performance of the material, despite its better crystallinity.

A survey of photocatalytic materials for environmental remediation.
TL;DR: This review illustrates the efforts in the search of alternative photocatalysts that are not based on TiO(2), with some exceptions concerning particularly innovative modifications as nanoassembled TiO-based composites with active carbon, graphite and fullerene.

Alkali‐Metal‐Promoted Pt/TiO2 Opens a More Efficient Pathway to Formaldehyde Oxidation at Ambient Temperatures
Changbin Zhang,Fudong Liu,Yanping Zhai,Hiroko Ariga,Nan Yi,Yongchun Liu,Kiyotaka Asakura,Maria Flytzani-Stephanopoulos,Hong He +8 more
TL;DR: A novel alkali-metal-promoted Pt/TiO2 catalyst is reported for the ambient destruction of HCHO, significantly promoting the activity for the HCHO oxidation by activating H2O and catalyzing the facile reaction between surface OH and formate species to total oxidation products.

Tailored Titanium Dioxide Nanomaterials: Anatase Nanoparticles and Brookite Nanorods as Highly Active Photocatalysts
TL;DR: In this paper, the photocatalytic activity of pure anatase nanoparticles, of anatase/brookite mixtures, and of pure brookite nanorods has been assessed by hydrogen evolution from aqueous methanol solution as well as by the degradation of dichloroacetic acid (DCA) in an in situ OH− source.
