中文摘要	the redox behaviours of 12-molybdophosphoric acid (12-mpa) and 12-molybdosilicic acid (12-msa) in aqueous acid media are characterized at the carbon fiber (cf) microelectrode. the preparation of cf microelectrode modified with 12-mpa or 12-msa monolayer and the oxidation-reduction properties of the modified electrode in aqueous acid media or 50% (v/v) water-organic media containing some inorganic acids are studied by cyclic voltammetry. 12-mpa or 12-msa monolayer modified cf microelectrode with high stability and redox reversibility in aqueous acidic media can be prepared by simple dip coating. the cyclic voltammograms of 12-mpa and 12-msa and their modified cf microelectrodes in aqueous acid solution exhibit three two-electron reversible waves with the same half-wave potentials, which defines that the species adsorbed on the cf electrode surface are 12-mpa and 12-msa themselves. the acidity of electrolyte solution, the organic solvents in the electrolyte solution, and the scanning potential range strongly influence on the redox behaviours and stability of 12-mpa or 12-msa monolayer modified electrodes. on the other hand, the catalytic effects of the 12-mpa and 12-msa and chlorate anions in aqueous acidic solution on the electrode reaction processes of 12-mpa or 12-msa are described.
