Photocatalytic Reduction of NO with Ethanol on Ag/TiO2
نویسندگان
چکیده
The effect of illumination on the surface interaction and the reaction between NO ? C2H5OH was investigated on TiO2 and Ag/TiO2. By means of Fourier transform infrared spectroscopy the formation of an absorption band at 2,210 cm was observed on pure TiO2, which was attributed to the NCO species. Similar measurements on Ag/TiO2 produced another spectral feature at 2,170 cm, which was assigned to the vibration of NCO bonded to Ag. These absorption bands formed more easily on oxidized than on reduced surfaces. Study of the catalytic reduction of NO with ethanol showed that the illumination of the system induced the reaction even at room temperature.

Formic Acid Decomposition Using Synthesized Ag/TiO2 Nanocomposite in Ethanol-Water Media Under Illumination of Near UV Light
The effect of ethanol-water media on the synthesis of Ag/TiO2 nanocomposite was investigated with 0.05, 0.1 and 0.5 (wt.%) of Ag content. Ethanol was used as hole-scavenger enhancing the photodecomposition of Ag+ ions under illumination of near-UV light. The nanocomposites were further calcined to 300˚C and 400˚C under controlled atmosphere. The synthesized nanocomposites were tested for photoc...

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...
