composites of π-stacking materials with low-dimensional metal oxide nanoblends for photocatalytic hydrogen production

Nanoblends of conjugated materials doped with low-dimensional metal oxides employing a scalable manufacturing process are discussed. the morphology, crystal structure and photocatalytic property of the nanoblends comprising of π-stacking materials namely polyaniline (pani), polythiophene (pth), graphene oxide (go) doped with metal oxide fe–tio2 to form fe–tio2/pani, fe–tio2/go and fe–tio2/pth nanostructures were studied in detail. the process includes wet chemical synthesis of the inorganic counterparts followed by mash blending technique to procure the low-dimensional nanoblends. the optical absorption characteristics of the above samples were studied by uv spectra. furthermore, the samples are characterized by xrd, ftir, sem-edax and tem analysis. the obtained nanoblends were utilized as photocatalyst for hydrogen production and a rational comparison was made with the procured fe–tio2 nanoblends. the assessment of the photocatalyst was also carried out. among the prepared nanoblends, fe–tio2/pth has good photocatalytic activity and shows maximum efficiency of 15.83% towards photocatalytic hydrogen production which can be ascribed to increased surface area as a result of texturing attributes. the long-term stability of the photocatalyst was confirmed by the catalytic stability tests.
