Titanium metal, photoelectron

The interactions between the anions and the Ti02 surface have also been investigated by other, more direct techniques than the potentiometric titrations. Thus, Sanchez and Augustynski have employed X-ray photoelectron spectroscopy to examine the adsorption of a series of anions onto titanium dioxide films of two kinds the relatively thick (10-15 nm) films, obtained by thermal decomposition of an alcoholic TiCl4 solution, and the natural, thin (15-20 A) films covering the surface of titanium metal. The Ti02 films of the first kind, supported onto Ti metal, have been extensively used as electrode materials in electrochemical and photoelectrochemical studies ...

Previous studies have shown that a trend exists in the behavior of some evaporated metals on polyimide surfaces x-ray and ultraviolet photoelectron (XPS, UPS) as well as high resolution electron energy loss (HREELS) measurements have indicated that while for some metals such as aluminum, titanium and chromium there is bond formation with the PMDA carbonyl oxygen of the polyimide (2, 10-13). other metals such as copper, palladium and gold undergo little reaction or interaction (10,12,14,15). It has, however, since been postulated that metals, in order to adhere well at all to a polymer under a wide variety of conditions, must form metal- polymer bonds (10). 

In the work by Fadeeva et al. (2011) and Fadeeva (2014), X-ray photoelectron spectrometry (XPS) analysis was performed to compare the chemical composition of a base metal (titanium) and noble metal (platinum) before and after laser structuring (Table 1).These XPS measurements were performed approximately 2 months after the laser structuring had taken place. The untreated, as well as laser structured samples, were stored under normal ambient conditions.
