X-ray photoemission spectroscopy and X-ray absorption spectroscopy demonstrated that the mixed film can be precisely adjusted by the composition of the solution used for co-adsorption of C12 and TMPP. The monolayer formed from the C12/TMPP = 1/10,000molmol solution contains only TMPP moieties, while that from the 1/ 1000 solution is mostly TMPP with a few percent of C12. The monolayer formed from the 1/100 solution contains a minor amount of TMPP, and that from the 1/10 solutions consists exceptionally of Cl 2 moieties [18].

All analytical methods that use some part of the electromagnetic spectrum have evolved into many highly specialized ways of extracting information. The interaction of X-rays with matter represents an excellent example of this diversity. In addition to straightforward X-ray absorption, diffraction, and fluorescence, there is a whole host of other techniques that are either directly X-ray-related or come about as a secondary result of X-ray interaction with matter, such as X-ray photoemission spectroscopy (XPS), surface-extended X-ray absorption fine structure (SEXAFS) spectroscopy, Auger electron spectroscopy (AES), and time-resolved X-ray diffraction techniques, to name only a few [1,2]. 

Suitable characterization techniques for surface functional groups are temperature-programmed desorption (TPD), acid/base titration [29], infrared spectroscopy, or X-ray photoemission spectroscopy, whereas structural properties are typically monitored by nitrogen physisorption, electron microscopy, or Raman spectroscopy. The application of these methods in the field of nanocarbon research is reviewed elsewhere [5,32]. 

We next discuss x-ray absorption studies. To put matters in context, it is useful to understand that conventional studies using Auger electron spectroscopy (AES) and x-ray photoemission spectroscopy (XPS) can be carried out only ex situ in high vacuum after electrochemical treatment since the techniques involve electron detection. X-ray absorption spectroscopy can, in contrast, be used for valence and structural environment studies. As x-rays only are involved, they can be carried out in situ in an electrochemical or similar cell. 

Adsorption and oxidation of NO adlayers on Pt(lll) was studied by using in situ surface X-ray diffraction and ex situ X-ray photoemission spectroscopy [86]. Molecular adsorption of NO was observed independently of the preparation of the adlayer.

The state of dispersion of Tiiv in TS-1 has been confirmed by X-ray photoemission spectroscopy (Carati et al., 1990). The Ti 2p peak, which in anatase is at 458.4 eV, is shifted to 460.2 eV in TS-1 (Fig. 10). Such a high binding-energy value for a Ti 2p electron is ascribed to a relaxation effect observed when photoemission occurs from a highly dispersed system or an isolated atom.
