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.

TL;DR: In this article, the presence of metal ion dopants in the TiO_2 crystalline matrix significantly influences photoreactivity, charge carrier recombination rates, and interfacial electron-transfer rates.

TL;DR: A thorough review of alternative non-iron Fenton catalysts and their reactivity towards hydrogen peroxide activation is presented, describing in detail the complex mechanisms and emphasizes on practical limitations influencing their environmental applications.

TL;DR: In this paper, a review of surface-modified TiO2 photocatalysis based on photo-induced interfacial charge transfer has been conducted, which is mainly focused on environmental remediation, and various surface modifiers are classified according to the kind of surface modifiers and their effects on photocatalytic reaction mechanism and kinetics are discussed in detail.

TL;DR: This is the first quantitative demonstration that the concentration of OH radicals and the biocidal activity is linearly correlated, which indicates that the OH radical is the primary oxidant species responsible for inactivating E. coli in the UV/TiO2 process.
