Synthesis of a novel cone-shaped CaAl-layered double hydroxide (LDH): its potential use as a reversible oil sorbent

摘要

A novel cone-shaped superhydrophobk and oleophilic CaAl-LDH intercalated with dodecyl sulphate (DS~-) anions was synthesized from calcium dodecyl sulphate as a precursor via a one-step hydrothermal method. The synthesized LDH has been successfully utilized in mopping and regeneration of oil from oil-water mixtures.
