摘要
The CuFe2O4 nanoparticle has been successfully synthesized from bio-mediated (Aloe-Vera) combustion process. The structural characterization of synthesized nanoparticle was achieved by spectral-characterizations viz; XRD, SEM, FT-IR and optical examinations. The XRD studies displays a spinel cubic phase development of nanoparticle and its average-particle size (19.3 nm). Low band gap energy of synthesized nanoparticle has been recorded to be 2.84 eV using UV–Visible absorption spectroscopy, which impacts to higher photodegradation efficiency. The potential photocatalytic activity of synthesized nanoparticle was examined using Malachite Green (MG) organic dye as a model, which is performed under specific quantities of stock solution (60 ppm) and obtained nanoparticle (50 mg). The photodegradation efficiency of synthesized material was evaluated for MG dye degradation achieved with 87.5% at 140 min under Sun-light. The excellent oxidation-reduction peak potentials were observed for synthesized spinel ferrite nanoparticle modified with carbon paste investigated by electrochemical analysis using 0.1 M KCl in the different scan rates 0.01–0.05 V/s. The charge-discharge studies of CuFe2O4-graphite electrode at current density (0.4 A/g) was discussed which is well correspondence to pseudo-capacitive behaviour. The synthesized NPs through bio-resources extract has become a potential new insight into multiple practical applications.
