• W2004286191 abstract "To probe the origin of the unique functions of titanium dioxide (TiO2) nanoparticles observed in photocatalytic reactions, structures of Ti atom sites in titanium dioxide (TiO2) nanoparticles with different sizes were studied by Ti K-edge XAFS (X-ray absorption fine structure). Compared to the bulk TiO2 structure, a shorter Ti−O distance from surface TiO2 resulting from Ti−OH bonding was observed. The XAFS spectra also revealed an increasing disorder of the lattice with decreasing sizes of the nanoparticles based on a coordination number decrease for the third-shell O atoms as well as changes in relative intensities of preedge peaks A1, A2, and A3. However, the Ti sites largely remain octahedral even in the 30 Å diameter particles. These results imply that the increasing number of surface Ti sites as well as possible corner defects in small nanoparticles may be the main cause of the unique surface chemistry exhibited by nanoparticles of TiO2. XAFS was also used in monitoring the photoreduction reaction products of Cu2+ and Hg2+ on TiO2 nanoparticle surfaces, with or without surface adsorbers, alanine (Ala) and thiolactic acid (TLA). Ala dramatically enhanced photoreduction of Cu2+ on TiO2 nanoparticle surfaces, whereas thiolactic acid did not affect or even hindered Hg2+ photoreduction. Although both surface adsorbers chelated with the metal ions in the absence of TiO2 nanoparticles, this chelation was drastically changed in the Cu−Ala complex but was largely retained in the Hg−TLA complex when TiO2 was present. This may correlate with the different effects of the adsorbers on the photoreduction of the metal. Our experimental results suggest that a proper balance between the affinities of the adsorber to the metal ions and to the surface Ti atoms of TiO2 may be one of the keys in selecting a surface adsorber for enhanced photoreduction efficiency." @default.
