使用Phi 5000 versa探针,X射线源为 al Kα(1486.6 ev),测试样品以C1S的结合能进行校准。 结合图谱测定催化剂表面的元素组成及各元素的价态。
Using the Phi 5000 versa probe with an X-ray source of al Kα(1486.6 ev), the test sample was calibrated at the binding energy of C1S. The composition and valence states of the elements on the catalyst surface were determined by spectrogram.
