Abstract

Nanometer-sized particles of MoS2 were synthesized on (100), (001), and (110) surfaces of rutile TiO2. Molybdenum oxide was deposited on the TiO2 substrates and then sulfided to simulate the preparation of industrial catalysts. The nanoparticles which appeared on the sulfided surfaces were assigned to MoS2 particles. The topography of the nanoparticles was observed by atomic force microscopy (AFM) and by transmission electron microscopy (TEM). The number density of the nanoparticles was related to the surface energy of the substrates through the population of nucleation centers. On the TiO2(110) surface, AFM and TEM images assignable to MoS2 crystals edge-bonded to the substrate were observed. The coincidental lattice spacings of MoS2 and this particular surface were related to the observed edge-bonded growth. [DOI: 10.1380/ejssnt.2004.32]
