纳米结构修饰电极及其电化学界面微非均相电子转移

The research work on nanostructure physics showed that the electronic structure of metal and semiconductor clusters is different from corresponding solid. There are less atoms in metal clusters,where the state density is multistructures. The electron in Fermi level would be affected by the size of nanoparticles. In this case, the behavior of nanods or nanostructured electrods is different from that of solid electrods. We prepared Ag-exchanged zeolite electrods, suspended electrods of Ag/SiO2 nanoparticles, the transparent film electrods of Ag/SiO2 and studied the behavior of the electrods by CV method and so on; compared property differences between nanods and solid electrods, discussed related mechanisms also.
