Single‐walled carbon nanohorns have received great interest for their unique properties and diverse potential applications. Herein, we demonstrated the feasibility of single‐walled carbon nanohorns incorporated poly(styrene‐divinylbenzene) monolith as the stationary phase for capillary electrochromatography, which were prepared by one‐step in situ copolymerization. Single‐walled carbon nanohorns were dispersed in styrene to give a stable and homogeneous suspension. The monolithic column gave effective separation for a wide range of aromatic compounds, which was based on hydrophobicity and π–π electrostatic stacking of single‐walled carbon nanohorns. The precisions of migration time and peak area varied in the ranges of 1.4–1.9% for intraday trials and 1.7–3.5% for interday trials, and 3.2–6.7% for intraday trials and 4.1–7.4% for interday trials, and 3.6–7.2% for inter‐column trials and 5.2–21.3% for inter‐column trials, respectively, indicating the good reproducibility of single‐walled carbon nanohorns embedded monolithic columns.
