Silver (Ag) nanoparticles with an average size of ca. 10 nm were uniformly deposited on the surface of α‐Bi 2 Mo 3 O 12 nanorods by using an ultrasound sonication method. Ultrasonic irradiation of preformed α‐Bi 2 Mo 3 O 12 spherical nanoparticles (ca. 200 nm) in pyridine resulted in α‐Bi 2 Mo 3 O 12 nanorods (ca. 100 nm diameter). Further, sonication of the mixture of α‐Bi 2 Mo 3 O 12 nanorods and Ag 2 O in pyridine yielded a nanocomposite of α‐Bi 2 Mo 3 O 12 nanorods with deposited Ag nanoparticles and pyridine. Calcination of the nanocomposite at 450 °C afforded pyridine‐free α‐Bi 2 Mo 3 O 12 nanorods with deposited Ag nanoparticles. A plausible mechanism is proposed. The crystallized Ag nanoparticles are uniformly deposited on the surface, with bismuth (Bi) as the preferential binding site, as revealed by time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS). Structural, compositional and morphological characterization of the products is carried out by using transmission electron microscopy, energy‐dispersive X‐ray analysis, scanning electron microscopy, thermogravimetric analysis, X‐ray diffraction, X‐ray photoelectron spectroscopy and TOF‐SIMS.
