Nanoarchitectonics of CdFe2O4 nanoparticles with different morphologies synthesized using a thermal decomposition approach and studies of their peroxidase-like activity

“…The UV-vis DRS spectra of CdFe 77,78 In the present study, the band gap of CdFe 2 O 4 nanoparticles decreases as their crystallite size increases (quantum confinement effect). 73,76 Magnetic properties…”

Green Photocatalytic Degradation of Industrial Effluent using CFN‐800 as a Visible Light Photocatalyst

“…From XRD, we calculated the percentage of porosity [35] of the CFN‐800 photocatalyst and it was found to be 89 %. The highly pores nature of CFN‐800 may help the hydroxyl radical and superoxide ions to diffuse faster inside the nanoparticles and increase the photocatalytic activity [30] …”

“…Among various ferrites, Cd ferrites are known to have small bandgap (1.97 eV) and well‐charge transport characteristics [27] . Various literature reports showed that most of the discussed applications of Cd ferrite are as gas‐sensing [28] materials, but much less attention has been given for the application of photocatalytic dye degradation [29–34] . Thus, considering the above problems and motivated by the charge transport and low bandgap property of Cd ferrites, in the present work, our objectives are to provide a facile, simple, and cost‐effective methodology for the production of Cd ferrites having chemical and thermal stability.…”

[29][30][31][32][33][34] Thus, considering the above problems and motivated by the charge transport and low bandgap property of Cd ferrites, in the present work, our objectives are to provide a facile, simple, and cost-effective methodology for the production of Cd ferrites having chemical and thermal stability. Further, we aim to use the prepared Cd ferrite as a recyclable and reusable heterogeneous catalyst for the degradation of BBF dye in water-based conditions via sunlight exposure.…”
