Carbon Domains on MoS₂/TiO₂ System via Catalytic Acetylene Oligomerization: Synthesis, Structure, and Surface Properties.

ABSTRACT: Carbon domains have been obtained at the surface of a MoS₂/TiO₂ (Evonik, P25) system via oligomerization and cyclotrimerization reactions involved in the interaction of the photoactive material with acetylene. Firstly, MoS₂ nanosheets have been synthesized at the surface of TiO₂, via sulfidation of a molybdenum oxide precursor with H₂S (bottom-up method). Secondly, the morphology and the structure, the optical and the vibrational properties of the obtained materials, for each step of the synthesis procedure, have been investigated by microscopy and spectroscopy methods. In particular, transmission electron microscopy images provide a simple tool to highlight the effectiveness of the sulfidation process, thus showing 1L, 2L, and stacked
