為什么能用標準電勢來估計空穴電位?
|
|
”Generally, in a valence band formed by Bi3+, holes formed by photoexcitation are regarded as Bi5+ (or Bi4+). Although a redox potential in an aqueous solution is different from that in solids, a standard redox potential of Bi2O4/BiO+ (BiV/BiIII) (E°=+1.59 V at pH 0) could make sense for a rough estimation of the oxidation potential of hole (Bi5+) photogenerated in the Bi2WO6 photocatalyst. “ 在”Visible-Light-Induced Degradation of Rhodamine B by Nanosized Bi2WO6“(Hongbo Fu, Chengshi Pan, Wenqing Yao, and Yongfa Zhu——J. Phys. Chem. B 2005, 109, 22432-22439)文獻中分析電位時,用BiV/BiIII的標準電勢來估計Bi2WO6中光生空穴的電位(引用文獻”Weast, R. C.; Handbook of Chemistry and Physics; CRC Press: Boca Raton, FL, 1988“)。 這點我不懂,其引用的參考文獻”Handbook of Chemistry and Physics“是一本英文巨著(1760頁),我都不知道在文中哪個地方找相關(guān)論述。哪位大神能指點下?(為什么能這樣估算?對于其他Bi系的光催化劑材料,分析電位時,是不是也能這樣估算?為什么?) 謝謝指點。! |
