The valence states of Cr3+/Cr2+ redox reaction products and Au and Pb catalysts deposited on glassy carbon electrode ( GCE ) and their catalytic characterestics for Cr3+/Cr2+ redox reaction were studied by XPS.

• 本文研究玻碳电极(GCE)表面Cr~(3+)/Cr~(2+)氧化还原反应产物和沉积的Au、Pb催化剂的价态以及它们对Cr~(3+)/Cr~(2+)反应的催化作用。 XPS研究结果表明,Cr~(3+)/Cr~(2+)氧化还原反应产物无Cr~0或其它价态的化合物生成。
