N2 - Molybdenum disulfide (MoS2) has been historically used as a hydrodesulfurization (HDS) catalyst and industrial lubricant. Because of its 2D nature and unique properties, MoS2 is being considered for new applications in catalysis and electronics. In addition, there is great interest in designing new physical forms of MoS2 that will allow for improved implementation of its properties, such as a continuous porous monolithic form. In this work, we report a new synthesis method to fabricate continuous, centimeter-sized, open cell hybrid foam (monolith) that consists of molybdenum sulfide and carbon as its main constituents. The hybrid foam was characterized using XRD, electron microscopy (SEM and TEM), Raman, FTIR, and EELS spectroscopy. Furthermore, liquid adsorption of dibenzothiophene (DBT) in toluene solvent was used to test the foam affinity to adsorb organosulfur compounds. The monolith is of low density and exhibits high specific adsorption capacity compared to existing materials reported in the literature.
