Nanodispersed MoS2 and CoMoS2 materials containing metastable 1T MoS2 phase have been prepared by solvothermal technique, characterized with several physico-chemical methods and evaluated in the electrocatalytic hydrogen evolution (HER), thiophene hydrodesulfurization (HDS) and 1-pentene hydrogenation (HYD) reactions. The role of different factors in the stabilization of 1T MoS2 phase has been studied. Stability of 1T polymorph upon heating was followed by XPS and Raman spectroscopies and evolution of HER activity. The results of characterizations (Raman, XPS, TEM, XRD) converge to the conclusion that ethylene glycol intercalated between the MoS2 layers stabilizes 1T –MoS2 polymorph. When heated above 200 °C, the solids lose the intercalated ethylene glycol molecules and are transformed to 2 H –MoS2. The presence of cobalt does not influence the stability of 1T phase, but improves both HER and HDS performance due to formation of CoMoS species.
