Silvercoated WS2 nanotubes (NTWS 2) were successfully synthesized via two wet chemistry techniques. The first employs spontaneous silver nanoparticle growth resulting from an interaction of disulfide nanotubes with AgNO3 in aqueous suspensions at 100 C without any additional reducing agents or stabilizers. The second utilizes [Ag(NH3)2]OH complex to produce silver nanoparticles upon thermal decomposition. Both techniques are capable of producing AgNTWS 2 nanocomposites containing 5–60 nm silver nanoparticles tightly attached to the nanotubes’ surfaces. The hexagonal arrangement of sulfur atoms of the outer WS2 layer was postulated to facilitate crystallization of silver nanocrystals with hexagonal crystallographic system (4H–Ag). The physicalchemical model for spontaneous AgNP formation is proposed.
