In order to improve the dispersion of molybdenum disulfide (MoS 2) and enhance the performance of MoS 2 , two alginate-derived biomass carbon-MoS 2 (BC-MoS 2) composites: CMB/CMS, were prepared by introducing BC during the synthesis of MoS 2 by hydrothermal. The effects of different gels, times and temperatures of the synthesized BC-MoS 2 were investigated, and the adsorption capacity for methylene blue (MB), basic fuchsin (BF) and copper ions (Cu2+) was tested. The results indicated that the vertical growth of MoS 2 on the BC surface could be realized when using xero-gel, while the BC and MoS 2 were mixed uniformly when using wet-gel. Compared with MoS 2 , the hydrophilicity and water dispersibility of BC-MoS 2 were greatly improved, and BC-MoS 2 had better adsorption capacity for MB/BF/Cu2+ (99.61/86.83/60 mg/g). The adsorption mechanism exhibits that the adsorption force of BC-MoS 2 on MB/BF is mainly based on the electrostatic force, and the adsorption on Cu2+ comes from the electrostatic force and the Lewis soft-soft interaction. This study dramatically enriches the application of transition metal chalcogenides and provides a meaningful reference for wastewater treatment. • Incorporation of biomass carbon to improve hydrophilic/water dispersibility of MoS 2 • Synthesis of MoS 2 composites with controllable morphology • Controllable synthesis of BC-MoS 2 by adjusting the hydrothermal temperature and time • Biomass carbon‑molybdenum disulfide synergistic adsorption was achieved [ABSTRACT FROM AUTHOR]
