| 4 | Direct Electrochemistry of Catalase on Single Wall Carbon Nanotubes Modified Glassy Carbon Electrode显示文摘Direct electrochemistry of catalase (Ct) has been studied on single wall carbon nanotubes (SWNTs) modified glassy carbon (GC) electrode. A pair of well-defined nearly reversible redox peaks is given at –0.48 V (vs. SCE) in 0.1 mol/L phosphate solution (pH 7.0). The peak current in cyclic voltammogram is proportional to the scan rate. The peak potential of catalase is shifted to more negative value when the pH increases. Catalase can adsorb on the SWNTs modified electrode. | QiangZHAO LunHuiGUAN ZhenNanGU QianKunZHUANG | 2005 | Chinese Chemical Letters2005，16，4： | 0 |
