AI Technical Summary

Technical Problem

Nanoparticles tend to aggregate in aqueous phases, leading to a decrease in active sites, uneven dispersion, and affecting adsorption efficiency and kinetics.

Method used

Activated carbon was used as a growth template to prepare a molybdenum disulfide/activated carbon composite adsorbent through solid-phase mixing and dispersant assistance. This ensured the uniform dispersion of molybdenum disulfide and utilized the stability of activated carbon and the effect of the dispersant to improve the dispersibility and adsorption performance of the nanomaterials.

Benefits of technology

This method achieves high dispersion stability of nanomaterials in the aqueous phase, ensuring sufficient collision and chemical exchange between the adsorbent and gold ions, thereby improving adsorption capacity and reaction kinetics.
