Long-range effects of noble metals on the photocatalytic properties of titanium dioxide

Article Abstract:

Long-range metallic effects on the photodegradation of the monolayers are studied. This is done with the help of titanium oxide and metals covered with self assembled monolayers and it is found that the presence of a metal in the vicinity of the photocatalyst does not increase its photoefficiency but, in fact, might reduce it significantly in comparison with a bare photocatalyst.

Remote photocatalytic activity as probed by measuring the degradation of self-assembled monolayers anchored near microdomains of titanium dioxide

Article Abstract:

The result of photogenerated oxidizing species formed on titanium dioxide well-defined microdomains is studied. Those are capable of including the mineralization of aliphatic chains anchored to inert silicon domains, even when these chains are located as far as 20 micro m away from the titanium dioxide microzones.

Photoinduced changes of adsorbed water on a TiO2 photocatalytic films as studied by (super 1)H NMR spectroscopy

Article Abstract:

(Super 1)H NMR spectroscopy is utilized as one of the most effective techniques to investigate adsorbed water on TiO2. The characteristics of adsorbed water and surface hydroxyl groups are extensively studied by temperature programmed desorption (TPD) and infrared reflection absorption spectroscopy (IRAS).
