Developing energy-efficient technologies for effective and economically viable water purification remains a pressing issue. Therefore, using molecular dynamics simulations, this study evaluates the efficiency of endohedral nickel-filled carbon nanotubes in removing petroleum contaminants from water. We simulated the molecular interactions of naphthalene, fluorene, and coronene with the nanotubes, revealing that nickel incorporation significantly enhances the adsorption capacity for petroleum contaminants [1]. Additionally, an increase in nickel content reduces system stability, facilitating adsorbed contaminants’ release during regeneration [2].

These findings suggest that nickel-filled nanotubes hold significant potential for water purification applications.
