“…For example, the issue of coordination of carboxylate anchors (mono versus bidentate) continues to be an important question in the efficiency of photoejection and stability of an adsorbed dye [707]. One of the prevalent structure sensitivity issues in organic photooxidation is the relative photoreactivities of various molecularly and dissociatively adsorbed states of molecules containing O-H bonds [714]. For example, based on IR, Liao et al [715] proposed that formic acid on P-25 was ∼53 times more photoactive than formate.…”

“…This is illustrated in the several of the references discussed above, with inhibition increasing at RH levels at which either a fully chemisorbed layer of water is established or at which physisorbed layers become stable. Examples of photooxidation studies on TiO 2 in which authors observed chemisorbed water acting as a site blocker include: CO [783], formaldehyde [1316], methanol [714], ethanol [890,897], acetaldehyde [1321], acetone [752,1026], ethylene [738,1322], 1-butene [1313,1314], butadiene [1311], toluene [941,943], and trichloroethylene [1006,1315]. As an example, Fig.…”

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.

“…Until now, the use of infrared (IR) spectroscopy has become one of the most powerful techniques to study the photocatalytic mechanism of degradation of VOCs with the advent of in situ accessories [10,11]. A greater variety of important information about the nature of adsorbed molecules and reaction intermediates can be obtained by using IR.…”

Photocatalytic degradation is a cost-effective technology for the removal of volatile organic compounds. However, the mechanism of photocatalytic degradation of volatile organic compounds on TiO 2 is still a challenging issue. Fortunately, infrared spectroscopy is a powerful technique, able to provide information about adsorption/desorption, intermediates/products, and interfacial reaction. The aim of this chapter is to review several aspects of our current understanding of the role of TiO 2 in the degradation of volatile organic compounds, by using in situ diffuse reflectance infrared Fourier transform spectroscopy. We firstly review the state of photocatalytic degradation of volatile organic compounds briefly. This is followed by a summary of in situ infrared techniques. The interaction of TiO 2 surfaces with vapor organic molecules and other species is then reviewed with the representative works in recent years. It ends with a brief future outlook on the mechanism of photocatalytic air purification of TiO 2 .
