Surface states of titanium dioxide nanoparticles modified with enediol ligands

Article Abstract:

Control of surface states of titanium dioxide nanoparticles using 2-(3,4-dihydroxyphenyl)ethylamine (dopamine) and 3,4-dihydrophenylacetic acid, which act as ligands to the under coordinated surface sites is demonstrated by electrochemical techniques. The deepest traps are found to be most reactive and are selectively removed by the addition of the ligands, which enhances the kinetics of electron accumulation in the film.

Light-induced charge separation and redox chemistry at the surface of TiO2/Host-guest hybrid nanoparticles

Article Abstract:

A study was conducted on the photoinduced charge transfer between guest molecules and hybrid TiO2/cyclodextrin nanoparticles using low-temperature EPR and cyclic voltammetry. The results show successful selective oxidation of ferrocenemethanol included in the hydrophobic cavity of a cyclodetrim molecule, followed with dissociation of an inclusion complex.

Radiolytically induced formation and optical absorption spectra of colloidal silver nanoparticles in supercritical ethane

Article Abstract:

Synthesis of colloidal silver nanoparticles in supercritical ethane at 80 degree C and 80-120 bars with methanol as cosolvent is observed. Results showed, by using pulse radiolysis colloidal particles, were stable for hours in supercritical ethane.
