Comment on "density functional theory study of triangular molybdenum sulfide nanocluster and CO adsorption on it"

Article Abstract:

The theoretical results reported by Zeng and others are compared with experimental infrared (IR) spectra of CO and new experimental results are presented demonstrating that the band at approximately 2110 [cm.sup.-1] can be assigned to monocarbonyl species. It is concluded that the strong [nu](CO) band at 2112 [cm.sup.-1] is not due to dicarbonyl species.

Effect of platinum nanocluster size and titania surface structure upon CO surface chemistry on platinum-supported TiO2 (110)

Article Abstract:

The effects of platinum nanocluster size and titania surface structure on carbon monoxide (CO) surface chemistry on platinum-supported titanium dioxide (TiO2) (110) are studied. The results suggest that the reduced surface has stronger interaction with CO molecules and leads to the dissociation of CO in the presence of platinum.

Preparation and comparison of supported gold nanocatalysts on anatase, brookite, rutile, and P25 polymorphs of TiO2 for catalytic oxidation of CO

Article Abstract:

Nanosized anatase, rutile, and brookite titania particles are successfully synthesized through sonication and hydrothermal methods. The results indicate that the gold particles supported on brookite are smaller than those on the other supports following the reaction and pretreatment sequences.
