Synthesis of multifunctional FeCo2O4 electrode using ultrasonic treatment for photocatalysis and energy storage applications

To overcome problem of energy crises, and water pollution, multifunctional nanoflower-like FeCo 2 O 4 is synthesized for energy storage and photocatalysis applications. The nanoflower-like FeCo 2 O 4 possesses charge transportation ability. The nanoflower-like morphology of FeCo 2 O 4 is designed by simple hydrothermal synthesis with use of probe sonicator. The systematic analysis is performed for verify relevance of surface characteristics with electrochemical and photocatalytic properties of FeCo 2 O 4 electrode. FeCo 2 O 4 exhibits hierarchical flower-like nanostructure with high surface area and appropriate pore volume, which increases specific capacitance (Cs) up to 1230 F g −1 with stability up to 5000 cycles. Degradation efficiency of crystal violet using FeCo 2 O 4 photocatalyst is reached up to 94.19% under sunlight irradiation for 160 min.
