| Abstract: | The catalytic effects of the silver ion on toluene oxidation by Ce4+ as well as the anodic generation of Ce4+ were investigated. The rates of toluene oxidation were first order with respect to both Ag+ and Ce4+. Argentic oxides formed on the surface of the platinum anode when Ag+ was present in the anolyte, which increased the activity of the electrode. About 3×10–3M of Ag+ was needed to obtain maximum current efficiency. |
