- As a consequence, the oxidation of sec butyl alcohol was inhibited by the presence of S ad . 相反 ;Pt电极表面S吸附原子的氧化会消耗表面氧物种 ;抑制仲丁醇的氧化 .
- The processes of adsorption and oxidation of sec butyl alcohol on Pt electrode and Pt electrodes modified with Sb and S (Pt/Sb ad and Pt/S ad ) were studied by using cyclic voltammetry and electrochemical quartz crystal microbalance (EQCM). 运用电化学循环伏安和石英晶体微天平研究了HClO4溶液中仲丁醇在Pt电极及以Sb和S吸附原子修饰的Pt(Pt/Sbad和Pt/Sad)电极上的电催化氧化过程 .
- In comparison with the case of Pt electrode, the oxidation peak potential of sec butyl alcohol on Pt surface modified with Sb was negatively shifted about 100 mV. On the contrary, the oxidation of S adatoms consumes oxygen species on Pt electrode surface. 与Pt电极相比 ;Sb吸附原子修饰的Pt电极使仲丁醇氧化的峰电位负移约 10 0mV .
