Geometrically Intricate Oxide-Based Heterostructure Over Flexible Platform: Morphology-Induced Catalytic Performance Enhancement Under UV Light Subhasish Thakur, Soumen Maiti, Shreyasi Pal and Kalyan Kumar Chattopadhyay Abstract Tailor-made heterostructural nanoform based on multiple low-dimensional frameworks not only offers manifold functionalities also bestows several novel interface phenomena. From the broad usage window of heterostruc- tures, photocatalysis is very significant nowadays. In this work, we have realized oxide-based hybrid comprising 1D TiO 2 –ZnO nanoform on flexible carbon cloth via facile chemical approach. Successful presentation of the hybrid over foldable platform was established via FESEM which discloses its typical morphology. To attain a clear insight of the elemental composition EDX analysis and elemental mapping of the hybrid was also carried out. Catalytic activity of the synthesized samples under UV light illumination was inspected taking Rhodamine B as the model contaminant where the heterostructure exhibited much-improved perfor- mance as compared to the individual structural building block. Prolonged separa- tion time of the photogenerated charge carriers in heterostructure ensures enhanced photocatalytic activity. Such work on morphology-induced catalytic performance enhancement will inspire the researchers toward creative designing of different photocatalyst comprising other multifunctional oxides.
