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.
