This study was used to evaluate the catalytic activity (CA) and bactericidal activity of α-MoO3 and Sm-g-C3N4-doped α-MoO3 composites prepared through an efficient, cost-effective coprecipitation route. Their characteristic studies verify the formation of α-MoO3 and its composites (3, 6, and 9 mL Sm-g-C3N4-doped α-MoO3), which showed high crystallinity, as confirmed by X-ray diffraction (XRD) analysis. The production of superoxide and hydroxyl radicals due to charge transfer through α-MoO3 and g-C3N4 eventually forms electrons in g-C3N4 and holes around α-MoO3. CA against Rhodamine B (RhB) in basic medium provides maximum results compared to acidic and neutral media. The bactericidal efficacy of the (9 mL) doped sample represents a greater inhibition zone of 6.10 mm against the negative bacterial strain Escherichia coli. Furthermore, in silico studies showed that the generated nanorods may inhibit DNA gyrase and dihydropteroate synthase (DHPS) enzymes.
