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