Studies of the low temperature oxidation of alloys by X-ray photoelectron spectroscopy: CuZn

Electrochemical and XPS study of 2-merсaptobenzothiazole nanolayers on zinc and copper surface

“…As mentioned above, the XPS Zn2p 3/2 peak for metallic state is undistinguishable from that of Zn 2+ [30][31][32][33][34][35][36][37][38]. In such cases, ZnLMM Auger transitions induced by X-ray radiation (Fig.…”

“…In many studies [28,[31][32][33][34][35][36][37][38] it has been shown that the Cu2p 3/2 peak positions of metallic copper (932.6 eV) and Cu 2 O (932.8 eV) almost coincide. These values differ considerably from those reported in [38] in which an attempt to separate the two states is done.…”

Oxidation of α-brass: A photoelectron spectroscopy study

“…On the surfaces exposed to O 2 , two components are clearly identified at 530.0 eV and 531.6 eV. The major component at lower binding energy (BE) is usually attributed in the literature to a bulk oxide [22,31,32]. The width of the component at 531.6 eV is larger (2.8 eV full width at half-maximum (FWHM) compared to 1.2 eV for the lower BE component) and the area ratio between the two components is almost constant at 2:1 during the oxidation.…”

“…The oxidation of brass single-and poly-crystalline samples has been studied by X-ray photoelectron spectroscopy (XPS) [22][23][24][25] and by nuclear methods [25,26]. However, no clear mechanisms have been evidenced for the initial stages of oxidation.…”

“…The electronic structure of the various phases of brass obtained by varying the Zn concentration has been the object of numerous investigations both theoretical [3][4][5][6][7][8][9][10] and experimental [11][12][13][14][15]. However, among the large number of studies related to the reactivity of brass [16][17][18][19][20][21][22][23][24][25][26][27][28][29], only few were focused on the early stages of the surface reactions [28,29]. Performing this fundamental work is essential in order to understand the mechanisms and the associated parameters that are controlling the formation and stability of such complex systems.…”
