Dual Functional Cobalt-doped CdFe2O4 nanoflakes for Promising Photocatalysts and Supercapacitor Electrodes

Modern economic society is rapidly developing, leading to an increase in global energy demand due to the unnecessary burn¬ing of non-renewable fossil fuels, leading to energy crises and change in climate due to the inevitable production of organic dyes. Herein, the sol-gel auto-combustion method was used to fabricate cobalt-doped cadmium ferrite (Co-CdFe2O4) nanoflakes with co¬balt 0.02%, 0.04%, 0.06%, 0.08% and 0.1% concentration. Prepared samples were characterized using XRD, SEM, UV-visible, and dielectric. XRD confirmed that pristine and Co-CdFe2O4 powder possessed spherical cubic crystal structure; no phase changes were observed after Co substitution. The dielectric constant, dielectric loss, and tangent loss were decreased at higher frequencies, and the effect of Co-doping was observed to change the dielectric properties significantly. After 35 minutes under visible light irradiation, the photocatalytic experiments presented exceptional photodegradation efficiencies against methylene orange (MO) (99.09%). The electrochemical results showed that the 0.1% Co- CdFe2O4 nanostructures offer an exceptional specific capacitance of 520.02 F/g, at of 1 mV/s scan rate. Such inexpensive and efficient photocatalytic electrode materials are required for energy storage applications and environmental protection.
