Electrochemistry of Porous Oxides and Related Materials

In contact with aqueous alkaline media, metal oxide electrochemistry is dominated by hydroxylation processes. However, in contact with acidic media, proton and cation insertion processes occur, eventually leading to complicated responses where reductive or oxidative dissolution processes frequently take place (Scholz and Meyer, 1998 Grygar et al., 2002 Scholz et al., 2005). As far as such processes involve disintegration of the porous structure of the material, electrochemically assisted dissolution processes will be taken only tangentially here. 

Finally, the electrochemistry of porous metal oxides prepared as films from anodic treatment of metal electrodes will also be discussed. Porous metal oxide films on electrodes have applications in a variety of fields, from corrosion protection to batteries and catalysis.
