Transfer of Photoinduced Electrons in Anatase–Rutile TiO2 Determined by Time-Resolved Mid-Infrared Spectroscopy
TL;DR: In this paper, the photogenerated electrons in the shallow states of anatase transfer to rutile across the anatase-rutile interface, but this does not exclude the possibility that the net electron transfer from ru...

Promotion of atomic hydrogen recombination as an alternative to electron trapping for the role of metals in the photocatalytic production of H2
TL;DR: Experimental evidence is provided that suggests an alternative pathway that does not involve electron transfer to the metal but requires it to act as a catalyst for the recombination of the hydrogen atoms made via the reduction of protons on the surface of the semiconductor instead.

Synthesis and UV−Visible-Light Photoactivity of Noble-Metal−SrTiO3 Composites
TL;DR: The photocatalytic activity of strontium titanate (SrTiO3) perovskite films has been examined and compared with that of commercially available titania (TiO2, Degussa P25) in the degradation of a model pollutant, Victoria Blue dye as discussed by the authors.

A low-cost, high-efficiency solar cell based on dye-sensitized colloidal TiO2 films
TL;DR: In this article, the authors describe a photovoltaic cell, created from low-to medium-purity materials through low-cost processes, which exhibits a commercially realistic energy-conversion efficiency.
Journal ArticleDOI
Environmental Applications of Semiconductor Photocatalysis
TL;DR: The slow pace of hazardous waste remediation at military installations around the world is causing a serious delay in conversion of many of these facilities to civilian uses as discussed by the authors, which is a serious problem.

Visible-Light Photocatalysis in Nitrogen-Doped Titanium Oxides
TL;DR: Film and powders of TiO2-x Nx have revealed an improvement over titanium dioxide (TiO2) under visible light in optical absorption and photocatalytic activity such as photodegradations of methylene blue and gaseous acetaldehyde and hydrophilicity of the film surface.
Atmospheric chemistry and physics: from air pollution to climate change.
TL;DR: In this article, the authors present a model for the chemistry of the Troposphere of the atmosphere and describe the properties of the Atmospheric Aqueous phase of single aerosol particles.
