Journal ArticleDOI
Explaining the Enhanced Photocatalytic Activity of Degussa P25 Mixed-Phase TiO2 Using EPR
TL;DR: In this paper, the role of rutile in mixed-phase titania photocatalyst was investigated by EPR spectroscopy, showing that the transition points between these two phases allow for rapid electron transfer from pure-phase rutiles to anatase.
Journal ArticleDOI
Surface Restructuring of Nanoparticles: An Efficient Route for Ligand−Metal Oxide Crosstalk
TL;DR: In this article, surface modification of nanocrystalline metal oxide particles with enediol ligands was found to result in altered optical properties of nanoparticles, and the surface modification results in a red shift of the semiconductor absorption compared to unmodified nanocrystites.
Journal ArticleDOI
Recombination pathways in the Degussa P25 formulation of TiO2: surface versus lattice mechanisms.
TL;DR: It is experimentally shown that upon band-gap illumination holes appear at the surface and preferentially recombine with electrons in surface trapping sites, which indicates that in mixed-phase TiO2, such as Degussa P25, a random flight mechanism of recombination predominates.
Journal ArticleDOI
Improving Optical and Charge Separation Properties of Nanocrystalline TiO2 by Surface Modification with Vitamin C
TL;DR: In this article, the structural and electrochemical properties of nanoparticles were found to be different from those of the corresponding bulk semiconductors, due to the specific binding of modifiers to "corner defects".
Journal ArticleDOI
Trapped holes on titania colloids studied by electron paramagnetic resonance
TL;DR: In this paper, an electron paramagnetic resonance (EPR) study of paramagnetic species formed on band gap irradiation of TiO 2 colloids, aqueous suspensions of anatase (Degussa P-25), and rutile (Aldrich) powders is reported.
