Preparation of Carbon Nanorods Based on Self- Aggregation of SDBS in The Kcl System

Introduction: This article presents a strategy for achieving structural retention of integrity after carbonization by encapsulating aggregates in a concentrated salt system, known as bound-in-situ carbonization. Methods: Sodium dodecylbenzene sulfonate (SDBS) was used as a carbon source, and the KCl system was introduced to segregate and protect the aggregates, which were then carbonized to obtain carbon nanorods (CNRs). The structural characterization of the materials was investigated using Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Photoelectron Spectroscopy (XPS), X-ray Diffraction (XRD), and Raman Scattering Spectroscopy (Raman). Results: The results showed that the prepared materials had a high degree of graphitization and were doped with oxygen (O), chlorine (Cl), potassium (K), and nitrogen (N) heteroatoms. Discussion: The CNRs were prepared in an open environment, and no additional protective gas was added during the preparation. Conclusion: The experiment was simple and efficient, realizing one-step preparation of carbon nanomaterials. Compared to traditional synthesis methods for carbon nanomaterials, this work demonstrated significant superiority and great potential.
