Journal ArticleDOI
TiO2 photocatalysis and related surface phenomena
TL;DR: The field of photocatalysis can be traced back more than 80 years to early observations of the chalking of titania-based paints and to studies of the darkening of metal oxides in contact with organic compounds in sunlight as discussed by the authors.
Journal ArticleDOI
Review of the anatase to rutile phase transformation
TL;DR: A comprehensive analysis of the reported effects of dopants on the anatase to rutile phase transformation and the mechanisms by which these effects are brought about is presented in this article, yielding a plot of the cationic radius versus the valence characterised by a distinct boundary between inhibitors and promoters.

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.

Synergism between rutile and anatase TiO2 particles in photocatalytic oxidation of naphthalene
TL;DR: In this article, a mixed solution of acetonitrile and water using various kinds of titanium dioxide (TiO 2 ) powders as photocatalysts and molecular oxygen as the electron acceptor was investigated.
Journal ArticleDOI
Influence of the preparation methods of titanium dioxide on the photocatalytic degradation of phenol in aqueous dispersion
TL;DR: In this article, commercial and homemade TiO{sub 2} samples were used as photocatalysts to prove that physicochemical features as determined by the origin and preparation methods affect the photocatalysis behavior, in addition to the semiconducting properties.
