Design of multifunctional C@FeO-MoO binary nanocomposite for applications in triphenylmethane textile dye amelioration via ultrasonic adsorption and electrochemical energy storage.

In this paper, we present the synthesis of C@FeO-MoO binary composite were prepared through the facile hydrothermal process. The ultrasonic aided adsorption efficacy was evaluated by studying triphenylmethane dye's adsorption potential. The ultrasonic aided adsorption capacity towards crystal violet was 993.6 mg/g, which is remarkably higher and best fitted with the Langmuir isotherm model and followed pseudo-second-order kinetics. The electrochemical studies working electrode have been prepared with 80 wt% active material, 10 wt% carbon black, and 10% polyvinylidene difluoride to evaluate energy storage characteristics. The C@FeO-MoO demonstrated an excellent specific capacitance of 40.94 F/g with better retention and stability, making it a potential cathode material for next-generation electrochemical energy storage devices.
