Synthesis of Co/MoS2 by Laser Pyrolysis and its Catalyst Activity

Abstract

Molybdenum sulfides (MoS 2 )are efficient hydrodesulfurization (HDS) catalysts widely used in crude oil desulfurization. This paper described the synthesis of MoS 2 and Co/MoS 2 nanomaterials by laser pyrolysis method. Here, we investigated two catalysts sample MoS 2 and Co/MoS 2 , which were active for deep hydrodesulfurization reaction. Sulfide catalysts were characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM), and tested in the dibenzothiophene (DBT) HDS reaction. It was found that pure MoS 2 and Co/MoS 2 nanomaterials was obtained with hollow spheres form. And Co/MoS 2 catalyst has much better initial activity compared to the reference commercial catalyst. 1
