Abstract

In contemporary research, “Heterostructure” assemblies play an important role in energy conversion systems, wherein the composite assemblies facilitates faster charge carrier transport across the material interfaces. The improved/enhanced efficiency metrics in these systems (electro/photo-electrochemical processes/devices) is due to synergistic interaction and synchronized charge transport across material interfaces. Herein, we report Type-I Heterostructure consists of N, S doped TiO2 and Fe2O3 for electrochemical crystal violet dye degradation studies. Synthesized N-S codoped TiO2/Fe2O3 composite heterostructured assemblies were fabricated on Titanium (Ti) substrate and used for electrochemical analysis. Complete decolourization was achieved with all the fabricated electrodes and a higher rate of degradation was achieved with composite electrode (Ti/TiO2/Fe2O3) in comparison to individual electrodes (bare Ti, Ti/TiO2, Ti/Fe2O3). Further, a probabilistic mechanism of degradation is proposed in support of the hypothesis. The outcomes of present work will have a profound effect on doped semiconductor heterostructure assemblies in degradation of complex dye molecules of industrial outlets
