Electrochemical and photocatalytic studies of Ta(3)N5-TaON-PEDOT-PANI nanohybrids

The present study deals with the synthesis, characterization, and testing of tantalum nitride- tantalum oxynitride (Ta3N5-TaON) coupled organic polymers (poly (3,4-ethylene dioxythiophene)-polyaniline; PEDOT-PANI) for the electrochemical oxidation and dye degradation applications. The ammonolysis fo...

From the analysis of the results, the Ta3N5-TaON-PEDOT-PANI nanohybrids showed excellent activity and stability towards MBZ oxidation and photocatalytic dye degradation, i.e., the highest dye degradation efficiency of > 97% was obtained.
