“…Isopropyl alcohol: Photooxidation of 2-propanol (isopropanol) presents an interesting case because the reaction exhibits near 100% selectivity toward acetone [721,722,[898][899][900][901][902][903][904]. Conversion of 2-propanol to acetone requires two oxidative steps, and the intermediate associated with the first step has not that been identified.…”

“…Several studies have shown the importance of gas phase O 2 in the conversion of 2-propanol to acetone [721,722,[898][899][900][901][902][903][904]. In particular, Brinkley and Engel [900][901][902] examined the photooxidation of 2-propanol on R TiO 2 (110) and (100) surfaces in UHV, and concluded that O 2 was necessary for photooxidation.…”

“…Similarly, Nakade et al [694] used adsorbed Li + to enhance the I − /I − 3 redox couple reaction through modification of the surface potential. Sakaguchi and coworkers [904] found that the degree of enhancement in acetone photooxidation on TiO 2 by 3+ lanthanides (Yb 3+ , Eu 3+ , Sm 3+ and Ce 3+ ) tracked the ionic radius of the metal ion, suggesting their role was electrostatic in nature.…”

a b s t r a c tThe field of surface science provides a unique approach to understanding bulk, surface and interfacial phenomena occurring during TiO 2 photocatalysis. This review highlights, from a surface science perspective, recent literature that provides molecular-level insights into photon-initiated events occurring at TiO 2 surfaces. Seven key scientific issues are identified in the organization of this review. These are: (1) photon absorption, (2) charge transport and trapping, (3) electron transfer dynamics, (4) the adsorbed state, (5) mechanisms, (6) poisons and promoters, and (7) phase and form. This review ends with a brief examination of several chemical processes (such as water splitting) in which TiO 2 photocatalysis has made significant contributions in the literature.

Facile preparation of C-modified TiO₂ supported on MCF for high visible-light-driven photocatalysis

et al. 2015

A green and facile approach is employed to prepare an efficient visible-light-driven photocatalyst by using mesocellular foams (MCF) as matrix, glucose as a carbon-modified source and TiO 2 as the catalytic active sites, which is denoted as C-modified TiO 2 /MCF. Characterization results reveal that nano-sized TiO 2 nanoparticles are loaded in the pore channels of MCF rather than aggregated on the surface of MCF. Furthermore, glucose is selectively covered on the surface of TiO 2 /MCF composites during the stirring process due to the excellent adsorption capacity of MCF, and then glucose can be transformed to the coke carbon through a hydrothermal process. In addition, a facile thermal treatment is adopted to enhance the visible light photocatalytic activity of TiO 2 /MCF composites. It is believed that the post-thermal treatment plays a significant role in controlling the carbon diffusion from the surface to the bulk of TiO 2 . Compared to traditional C-TiO 2 photocatalyst, the prepared Cdoped catalyst exhibits a stable carbon doping in TiO 2 , more excellent adsorption capacity and higher visible light photocatalytic activity owing to the special structure of supported mesoporous catalyst. This study implies that the novel photocatalyst has a large application prospect in photocatalytic water splitting, dye-sensitized solar cell and other fields.
