Electrocatalysis at Metal Oxides and Related Materials

In the case of metal oxides, the eventual electron transport between contiguous metal centers should involve the coupled transport of hydroxo and eventually oxo groups, namely  

With regard to electrocatalytic processes, it is pertinent to note that in the case of insulating oxides, there is, in general, no possibility of substrate permeation 

It is assumed that glucose experiences a keto-enol transformation to form an anionic enol species  

the electrostatic interaction between cationic species and the anionic glucose form can be taken as an important factor for promoting glucose oxidation. 

This applies when catalytic centers are incorporated as dopants to the lattice of the base porous material. In fact, site isolation of electroactive centers immobilized in microporous materials and doping units in inorganic supports appears to promote efficient electrocatalysis for a variety of analytically significant processes. Some remarks can be made
