Cost-effective aegle marmelos extract-assisted synthesis of ZnFe_2O_4:Cu~(2+) NPs: photocatalytic and electrochemical sensor applications

摘要

In the reported work, Zn_xFe_2O_4:Cu_(1-x)~(2+) nanoparticle (CZF NPs) was successfully synthesized from fabrication of copper (Cu~(2+)) doped ZnFe_2O_4 NPs by a facile one-pot green (Aegle Marmelos extract) assisted combustion approach. The structural characterizations were investigated by specific spectral techniques; Powder X-Ray diffractometer (PXRD) confirms the formation of spinel cubic nanocrystalline structure with crystallite size in the range 20-25 nm. The porous with spongy like structure morphology was noticed by Scanning electron microscope (SEM). The photocatalytic performance of CZF NPs (7 mol%) was examined by observing their potential role in photodegradation of Rhodamine B (Rh-B) dye (94%) under irradiation of UV-Visible light. Electrochemical study was conducted by graphite assisted with CZF electrode paste in 0.1 M KC1 electrolyte and performed as an excellent mechanism of charge-discharge supercapacitor nature with high responses towards the electrochemical sensor action for Mifepristone-Misoprostol.
