The resultant NCs showed excellent photocatalytic, antibacterial, anticorrosive, and magnetic characteristics. The use of FTIR, TEM, UV-visible, X ray diffraction, and SEM aids the structural examination of NCs. The synergistic pairing of ACT NPs with rGO exhibits enhanced photocatalytic, magnetic, anticorrosive, and antibacterial characteristics. The NCs exhibited paramagnetic character ( χ = 0.140) and increased induced current with applied magnetic field. The photo catalytic properties of NCs were examined for decomposing methylene blue dye in UV and Sunlight. 94.7 % and 70.5 % dye degradation was observed under UV and Sunlight after 335 and 110 min. of exposure, respectively. The Zone of Inhibition was examined against S. aureus (Gram-positive) and E. coli (Gram-negative) bacteria and was found comparable with standard antibiotics (Ampicillin) against S. aureus bacterial strain. The NCs show 99 %corrosion inhibition efficiency at a low concentration (10 ppm). The potential applications of ACT@rGO NCs in environmental rehabilitation, the medical field, anticorrosive coatings, and impure water purification, contribute toward the development of advanced nanomaterials-based devices.en
