摘要：

Appropriate conditions were selected to favour the non-destructive electroreductive deposition of [(HOAs)(4)Mo12O46](4-) on solid electrode surfaces. During the first several cyclic voltammetry runs on glassy carbon electrodes, the surface activity of this tetrameric complex anion was found to depend on the nature of the supporting electrolyte anion. Cyclic voltammetry, electrochemical quartz crystal microbalance (EQCM) and atomic force microscopy (AFM) results converge to indicate that stable and porous films are formed, which should be suitable for electrocatalysis studies on a molecular basis.
