▎ 摘　　要

In this work, molybdenum disulfide/reduced graphene oxide (MoS2/RGO) hybrids are synthesized by a spatially confined reaction to insert the growth of defect-rich MoS2 nanosheets within graphene to enable incorporation into the polymer matrix for the application in the removal of smoke particles and toxic volatiles. The steady-state tube furnace result demonstrates that MoS2/RGO hybrid could considerably reduce the yield of CO and smoke particles. The TG-IR coupling technique was utilized to identify species of toxic volatiles including aromatic compounds, CO, and hydrocarbons and to investigate the removal effect of MoS2/RGO hybrids on reducing toxic volatiles. The removal of smoke particles and toxic volatiles was attributed to the adsorption capacity derived from edges sites of MoS2 and the honeycomb lattice of graphene, as well as the inhibition of nanobarrier resulting from two-dimensional structure. The work will offer a strategy for fabricating graphene-based hybrids by the space-confined synthesis and exploiting the application of space-confined graphene-based hybrid.
