Effect of precursors on the growth and physiochemical properties of bio-mimetic ZnFe2 O4 nanocomposites for photoelectrochemical application

| description | Zinc ferrite (ZnFe2
O4
) photocatalysts have been prepared with different types of zinc precursors using the bio-mimetic
synthesis method. The kapok fibre (Ceiba pentandra (L.) Gaertn) used as a sacrificial template. The physiochemical of
prepared bio-mimetic materials were carried out thoroughly in this work. The FESEM analysis in mimetic zinc ferrite
catalysts shows a distinctly different structural transition under different precursors conditions. The acetate precursor
formed a hollow tubular structure while other precursors formed a hierarchal fibril structure. X-ray diffraction analysis
showed a distinctly different phase transition while UV-Vis spectroscopy recorded variable optical properties beneath
different precursor conditions. The EDX and ATR-FTIR spectroscopy confirmed the formation of the pure composite
after the annealing process. Different type of precursors that used have leads to tuneable of the magnetic properties of
the prepared materials. Electrophoretic deposition (EPD) method has been used to fabricate the synthesized materials
as photo-electrodes on the FTO substrate then evaluated for photoelectrochemical (PEC) application. Changing
the precursors in the preparation method show a significant effect on physicochemical and PEC performance. The
morphology and surface structure of the prepared catalysts are correlated with the alteration of the precursors, then
attributed to the charge transfer properties of the photocurrent density in PEC system. The bio-templated zinc ferrite
catalysts are promising photoanode in the photocatalytic activities. It is interesting to note that the various forms
of multi-structure such as hollow fibril core-shell offers an enormous impact in designing active photocatalyst with
superior performance. |
