Electrocatalytic Activity of Ti／TiO2 Electrodes in H2SO4 Solution

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