## Abstract On the surface: Adsorption of O~2~ at the surface oxygen vacancy (SOV) sites of TiO~2~ reconstructs the lattice oxygen (healing SOVs), resulting in a decrease of the photocatalytic activity of oxidizing CO over vacuumβpretreated TiO~2~ with increasing temperature (see scheme). Adsorptio

β¦ Synopsis
Thermal desorption of D, from oudized titanium surfaces, covered wnh various amounts of platurum, shows no detectable irreversible adsorpuon for up to three monolayers of Pt when the substrate tcmpersture is 130 K. Twelve monolayers of Pt gtve a substrate that adsorbs signdkant amounts of both CO 3nd Ha.

## Abstract Electrolytic fixation of CO~2~ was investigated by electrocarboxylation of organic halides (a), and four esters (I, II, III, IV) were obtained in moderate yields. Electrochemical reduction esterifications of RX in the presence of CO~2~ were carried out on nanocrystalline TiO~2~βPt elect
## Abstract Metallic platinum was photodeposited on TiO~2~ particles, and morphological characteristics of the Pt/TiO~2~ catalyst were determined. The dispersion of metallic platinum was uniform and did not alter the morphology of the TiO~2~ particles. However, absorbance of the Pt/TiO~2~ catalyst
Kinetic model results are presented for desorption of OH radicals formed during the reaction HI + fOz+HzO on Pt. The results are compared with recent experimental results using laser-induced fluorescence. Variation in the apparent activation energy for OH desorption with HZ/O1 ratio can be attribute
