The pure MoS 2 -carbon composites (MoS 2 -C) and Fe modified MoS 2 -carbon composites (Fe/MoS 2 -C) were successfully synthesized through a facile two-step hydrothermal method by adding soft template of CTAB and applied as piezocatalysts to degrade Rhodamine B. The as-obtained catalysts were characterized by the X-ray diffraction (XRD) and scanning electron microscope (SEM). The results indicated the hybrids have large surface area, mesoporous structure, more edges and unsaturated S atoms. By comparing the muffle furnace samples (open air calcination) with the tube furnace one (closed Ar calcination), Fe/MoS 2 -C catalysts with tube furnace show the higher degradation activities (12.8% versus 5.8%). The possible degradation mechanisms are also discussed.
