Abstract Constructing novel multifunctional materials is a promising approach to boost the catalytic activity and electrochemical performance simultaneously. Herein, hydrothermal synthesized FeVO 4 nanosized particles dispersed on reduced graphene oxide (rGO) through cost‐effective simple sonochemical assisted route are developed as an efficient material for photocatalysis high‐value‐added supercapacitor applications. The were characterized structural morphological purity found be in single phase nanostructured. rGO‐FeVO composite shows excellent photodegradation of Levofloxacin (LVO) drug (100 % over 80 min) compared with owing bandgap visible region larger surface area. Further, optimized was employed into supercapacitors it showed 3 times higher capacitance (211.4 F/g at 0.5 A/g) (70.4 F/g) using half‐cell measurements. Moreover, symmetric (full cell; SSCs) device 109 A/g current density having high energy 13.6 Wh/kg power 450 W/kg. proposed proved its outcomes, which can open new opportunities develop such numerous future

Increasing energy demands in recent days have emphasized the need for development of reliable and efficient storage/conversion materials. Thereby, iron vanadate (FeVO4) was synthesized using a facile hydrothermal method, which is known to exhibit superior redox activity but its poor conductivity low charge transfer process affect overall performance. Incorporation graphene oxide into FeVO4 enhances conductivity, stability, composite due synergetic effect. multifunctional advanced electrocatalyst can be obtained. Spectroscopic techniques including X-ray diffraction, FE-SEM, EDAX-elemental mapping, Raman, photoelectron spectroscopy, HR-TEM analysis were done validate successful production high-purity products.
