Electron Spectroscopy Analysis

The steel surface of the flat was immersed in the solution of oxymolybdyl dithiophosphate (DDP)2Mo02 at a concentration of 2 wt% in a PAO synthetic lubricant base. The immersion time was 5 hr and the temperature was 100°C (Martin et al., 1996). The X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy analysis of the reaction film indicates that before friction, a relatively thick chemisorbed film composed of phosphorus (P) and sulfur (S) is present on the steel surface. The friction test was carried out in ultra high (UHV) analytical tribometer just after the analysis and in the same conditions as the untreated surface. 

The dimensions of anatase crystallites in the composite catalysts and of neat titania appear to be comparable. In fact, estimated crystallite sizes on composite catalysts are even lower than for neat titania, which suggests that the introduction of the different supports avoid Ti02 particle agglomeration. The surface areas of the composite catalysts are lower than those estimated theoretically in proportion to the Ti02 and support contents, meaning that there is a common interface between the two solid phases. This contact surface was confirmed by scanning electron spectroscopy analysis (Fig. 1).

Electron spectroscopy analysis is a scientific method that uses ionizing radiation, such as ultraviolet, X-ray, and gamma radiation, to eject electrons from atomic and molecular orbitals in a given material. The properties of these electrons are then interpreted to provide information about the system from which they were ejected.
