voltammetric charge%active surface%TiO2 electrode%electrochemistry
Ti/TiO2 electrodes were prepared with the polymeric precursor method (PPM). The structure and morphology of Ti/TiO2 electrodes were examined with XRD and ESEM. The voltammetric charge (q*) of Ti/TiO2 electrodes as cathode in 0.5 mol/L H2SO4 solution was investigated with cyclic voltammetry. It was found that the electrocatalytic activity of the Ti/TiO2 electrodes was affected by the structure and morphology of the Ti/TiO2 electrodes, in other words, was affected by the calcination conditions of preparing the electrodes. The value of q*ln was considerably larger than that of q*out,which means that the 'inner' active surface area was much larger than the 'outer' active surface area, and
'inner' active surface played a main role in the electrocatalytic activity of the Ti/TiO2 electrodes.
