EFFECT OF COMPOSITION ON THE POINT OF ZERO CHARGE OF RUO2+ TIO2 + CEO2 MIXED OXIDES

Abstract Mixed oxides of general composition RuO 0.3 Ti (0.7− x ) Ce x O 2 with 0 x 2 . Evidence for synergetic effects suggests that the three oxide components are in intimate chemical contact. The electrochemical surface area and the inner layer capacitance have also been derived from the charge-pH data.
