Ammonia oxidation was a prototype system, but subsequently a number of other oxidation reactions were investigated by surface spectroscopies and high-resolution electron energy loss spectroscopy XPS and HREELS. In the case of ammonia oxidation at a Cu(110) surface, the reaction was studied under experimental conditions which simulated a catalytic reaction, albeit at low... 

Electrochemical processes are always heterogeneous and confined to the electrochemical interface between a solid electrode and a liquid electrolyte (in this chapter always aqueous). The knowledge of the actual composition of the electrode surface, of its electronic and geometric structure, is of particular importance when interpreting electrochemical experiments. This information cannot be obtained by classical electrochemical techniques. Monitoring the surface composition before, during and after electrochemical reactions will support the mechanism derived for the process. This is of course true for any surface sensitive spectroscopy. Each technique, however, has its own spectrum of information and only a combination of different surface spectroscopies and electrochemical experiments will come up with an almost complete picture of the electrochemical interface. XPS is just one of these techniques. 

There have been significant advances in analytical capabilities (including high-vacuum surface spectroscopies and in situ spectroscopies) that can elucidate the structure and composition of catalysts, as well as the manner in which the reactants and products interact with the catalyst surface. Advanced supercomputers can facilitate quantum chemical calculations which should have predictive capabilities. Integration of spectroscopic characterization, quantum chemistry, and supercomputing is an important frontier area.

The situation is different for other carbon materials such as activated carbons. During activation of the precursor, partial oxidation of the carbon proceeds from the external surface of the carbon particle to the interior. Thus, the portion of the activated carbon particle close to the external surface is more severely activated than the interior and chemistry of the external and internal surface is most likely to be different. Before surface spectroscopy and gas adsorption data of OMCs are compared, the surface spectroscopic analysis of the carbon materials is reviewed very briefly. 

Along the same lines, it is worthwhile mentioning that even the two-dimensional contour plot obscures some important features of the true multidimensional PES. In order to illustrate this fact, consider the following argument. Some of the features in the PES can be probed by experiments the weakly physisorbed, molecularly and atomically chemisorbed species by surface spectroscopies and the activation barriers by molecular beam scattering experiments. Thus, much of the PES can be determined and the reader may wonder why one does not simply join these individual regions together and find the PES ...

It is not our purpose to discuss in detail the theory DFT, as there are many excellent reviews and books on that subject. Just a few examples of particular relevance to organometallic chemists apart from the myriad of applications that entail geometry optimization and reaction-coordinate evaluation include the use of DFT for prediction of ESR properties of metal complexes, modeling heterogeneous catalysts, time-resolved X-ray crystallography of metal complexes, " surface spectroscopy, and photofragment spectroscopy. ...
