Difference in extent of the Fermi energy and decrease of band-gap energy for three kinds of CNTs show that CNT with one end open is favorable for the preparation of field emission electrode.
The glassy carbon electrode was modified with chitosan by using the method of covalent-band reaction, and the anodic stripping voltammetric behavior of NO_2 ~ -at this modified electrode was examined.
用共价键合法把壳聚糖修饰在玻碳电极表面，研究了NO_2 ~ -在修饰电极上的阳极溶出伏安特性。
