The surface oxygen concentration of the α-Zr(O) determined by AES peak intensities shows a quite good agreement with the bulk oxygen concentration even after a prolonged Ar ion bombardment, whereas the depletion of oxygen is seen in ZrO 2. In XPS spectra, the conduction band of α-Zr(O)...

A model was developed for film dissolution that related the evolution of film thicknesses with the diffusion coefficients of O in Zr. The equation D = 3.1 × 10 -6 exp(-23750/ RT) cm 2/s is satisfied by the calculated coefficients. This expression is close to that obtained by Ritchie ...
The interfacial structure of Ti/single crystal Al 2O 3(0001), Ti/polycrystalline Al 2O 3, and Ti/single crystal MgO(001)system made by RF magnetron sputtering was investigated by using XPS combining with Ar + ion in situ etching in this paper. The results show that the reduction of Al...

xps中原子结合了电负性强的元素，结合能向高结合方向移动。Ce-Zr固溶体反应前后的XPS，已校准，XPS结果是反应后Ce3d结合能没有偏移，而Zr3d和O1s均向高结合能方向偏移，不知怎么解释。此外反应后催化剂是高温失活，无积碳。

Impregnation of V2O5 and heating of the V2O5/TiO2−ZrO2 catalyst beyond 600 °C results in the formation of ZrV2O7, with the simultaneous presence of the TiO2 rutile phase. However, the vanadia is in a highly dispersed state on the TiO2−ZrO2 mixed oxide support when calcined at less...
