Solution reactivity properties electrode transferal

Transfer of Solution Reactivity Properties to Electrode Surfaces... 

Returning to the question posed in the title, it seems evident that solution reactivity properties can be transferred to an electrode surface but with certain caveats. From the results described here, individual Ru-bpy sites appear to retain their intrinsic redox characteristics and their ability to undergo facile electron transfer. In addition, some of the more complex chemical reactions known for Ru-bpy complexes, including ligand-based reactions like RuNO+RuNC - RuONOo, and oxidation of azide, also occur in the films. It is also notable that the catalytic abilities of the Ru -NC>2 or RuIV-o groups can be transferred to the electrode-polymer interface. 

The electronic properties of CNTs, and especially their band structure, in terms of DOS, is very important for the interfacial electron transfer between a redox system in solution and the carbon electrode. There should be a correlation between the density of electronic states and electron-transfer reactivity. As expected, the electron-transfer kinetics is faster when there is a high density of electronic states with energy values in the range of donor and acceptor levels in the redox system [2]. Conventional metals (Pt, Au, etc.) have a large DOS in the electrochemical potential... 

EAB processes are an interfacial phenomenon EABs interact with the electrode inside the biofilm diffusive and reactive layers at the electrode surface. Extracellular electron transfer is directly related to these microscale layers, whereas diffusion processes above these layers are linked indirectly. Thus, we expect that the surface concentrations of the redox-active compounds and the local solution properties inside EABs are more relevant and critical than the corresponding values in the bulk. Correlating and fitting lines to bulk data may have little significance to the fundamental processes occurring inside EABs. Direct measurements inside EABs are preferred, such as measuring pH inside EABs or measuring the spectroelectrochemical properties of EABs [66, 138, 147]. This is especially important because the cell density inside some EABs is not uniformly distributed and predictions based on simple diffusion may not apply [120].
