Amorphous microporous titania modified with platinum(IV) chloride - a new type of hybrid photocatalyst for visible light detoxification

Article Abstract:

Research was conducted to examine the amorphous microporous metal oxides of titanium (AMM-Ti) modified with a few percent of a platinum(IV) halide. Preparation was performed through a sol-gel procedure while characterization was done using various surface analytical techniques. Results indicate that the dopant platinum halide initiates the reaction in both the visible and UV regions through homolytic cleavage of the platinum-halogen bond and subsequent charge-trapping by the amorphous titania matrix.

On the mechanism of radical C-N coupling in type B semiconductor photocatalysis: a high-pressure study

Article Abstract:

It has been established that a 2,5-dihydrofuran adsorbs onto cadmium sulfide through hydrogen bonding via surface [OH] and [SH] groups. A Bronsted acid-base interaction is suggested for azobenzene.
