Electrochemical properties of chemically synthesized SnO2-RuO2 mixed films

The SnO 2 –RuO 2 mixed films are prepared by successive ionic layer adsorption and reaction (SILAR) method. The SnO 2 films combined with RuO 2 are prepared by varying the deposition cycles of SILAR. The effect of combining SnO 2 with RuO 2 on structural, morphological and electrochemical properties is studied. It is observed that the crystalline nature of SnO 2 changed to amorphous with increase in RuO 2 deposition cycles. The morphology is also changed from fibrous-porous to compact after increasing RuO 2 deposition cycles. The specific capacitance of SnO 2 is increased from 4 to 185 F/g after combined with RuO 2 . The maximum utilization of RuO 2 is observed with specific capacitance of 1010 F/g.
