Exploiting electron storage in TiO2 nanoparticles for dark reduction of As(V) by accumulated electrons.
نویسندگان
چکیده
UV irradiation of an ethanolic sol of TiO2 nanoparticles produces a trapped Ti(III) centre and a noticeable Burstein shift. Direct evidence that the accumulated charges can drive the otherwise forbidden reduction of As(V) by conduction band electrons is presented.

Defective TiO2-supported Cu nanoparticles as efficient and stable electrocatalysts for oxygen reduction in alkaline media.
Nanocomposites based on TiO2-supported copper nanoparticles were prepared by a hydrothermal method where copper nanoparticles with or without the passivation of 1-decyne were chemically grown onto TiO2 nanocolloid surfaces (and hence denoted as CuHC10/TiO2 and Cu/TiO2, respectively). Transmission electron microscopy measurements showed that the size of the hybrid nanoparticles was 5-15 nm in di...
متن کاملReactivity of Trapped and Accumulated Electrons in Titanium Dioxide Photocatalysis
Electrons, photogenerated in conduction bands (CB) and trapped in electron trap defects (Tids) in titanium dioxide (TiO2), play crucial roles in characteristic reductive reactions. This review summarizes the recent progress in the research on electron transfer in photo-excited TiO2. Particularly, the reactivity of electrons accumulated in CB and trapped at Tids on TiO2 is highlighted in the red...
متن کاملCharge separation and catalytic activity of Ag@TiO2 core-shell composite clusters under UV-irradiation.
Photocatalytic properties of Ag@TiO2 composite clusters have been investigated using steady state and laser pulse excitations. Photoexcitation of TiO2 shell results in accumulation of the electrons in the Ag core as evidenced from the shift in the surface plasmon band from 460 to 420 nm. The stored electrons are discharged when an electron acceptor such as O2, thionine, or C60 is introduced int...
متن کاملاثر سیلیمارین بر اختلالات حافظه و یادگیری القا شده با نانو ذرات دیاکسید تیتانیوم
Background and Objective: Titanium dioxide nanoparticles (NP Tio2) are one of the most highly used particles in the world. They are used for biomedical and cosmetic goals. Several studies have shown that NP Tio2 induce oxidative stress in the hippocampus. Silymarin is a flavenolignan that is gained from seed of milk thistle (Silybum marianum) and due to its inhibition of free radicals, acts as ...
متن کاملEnhancement of Dye-Sensitized Solar Cells Efficiency Using Mixed-Phase TiO2 Nanoparticles as Photoanode
Dye-sensitized solar cell (DSSC) is a potential candidate to replace conventional silicon-based solar cells because of high efficiency, cheap cost, and lower energy consumption in comparison with silicon chip manufacture. In this report, mixed-phase (anatase and rutile nanoparticles) TiO2 photoanode was synthesized to investigate material characteristics, carriers transport, and photovoltaic pe...
