Effects of polyoxometalate and fluoride on adsorption and photocatalytic degradation of organic dye X3B on TiO(sub 2): The difference in the production of reactive species
Article Abstract:
The effects of polyoxometalates (POM) (PW(sub 12)O(sub 40)(super 3-) and fluoride both on the adsorption and photocatalytic degradation (PCD) of organic dye X3B on TiO(sub 2) in an aerated aqueous suspension are investigated. It is found that due to the surface occupation of these anions (POM or fluoride), the positive charges of TiO(sub 2) are greatly reduced, resulting in significant decrease in the adsorption of anionic dye X3B.

Interaction of CH4, CH3Cl, CH2Cl2, CHCl3, and CCl4 with O-terminated FeO(111)
Article Abstract:
A series of molecules including of CH4, CH3Cl, CH2Cl2, CHCl3, and CCl4 are used as probes to test the chemical reactivity of the FeO(111) surface. The temperature-programmed desorption spectra show no evidence of dissociative adsorption or chemical reaction between the substrate and the adsorbates.
