Abstract :
Ceria-based composites have been previously developed as functional electrolytes for high performance of solid oxide fuel cells that require high functional electrolyte materials that can provide high ion conductivity for sufficient current output. These composites display hybrid proton and oxygen ion conduction. We developed further composite electrolyte materials containing a catalyst such as rare earth elements; gadolinium (Gd3+), neodymium (Nd3+) and samarium (Sm3+) doped ceria (Ce0.8Gd0.2O2, Ce0.8Nd0.2O2 and Ce0.8Sm0.2O2) to investigate the electrochemical treatment of C.I. Reactive Orange 107. An experimental results showed that the nanomaterial plays an important role for the electrochemical oxidation of reactive dye, where Ce0.8Gd0.2O2, Ce0.8Nd0.2O2 and Ce0.8Sm0.2O2 lead complete mineralization of selective dye. The results indicate that the overall performance in these schemes of operation is successful.
