Single-walled carbon nanotubes based on cyclopentadienyl iron dicarbonyl dimer: synthesis, physicochemical and adsorptive properties

This work explores the methods for synthesizing carbon nanotubes using cyclopentadienyl iron dicarbonyl dimer (Cp2Fe2(CO)4) as a catalyst, as well as their physicochemical properties and potential applications.The synthesis was carried out via chemical vapor deposition using Si and copper substrates.The growth mechanisms, morphology, and structural characteristics of the nanotubes were studied using transmission and scanning electron microscopy (TEM, SEM), as well as Raman spectroscopy to analyze defects and chirality of the nanotubes.The resulting carbon nanotubes exhibit exceptional mechanical, electrical, and thermal properties, such as high strength, conductivity, and large specific surface area, which opens up their application in electronics, sensors, supercapacitors, and other high-tech devices.Additionally, the adsorptive properties of the synthesized nanotubes were investigated, demonstrating high efficiency in capturing various pollutants and gases.Functionalization, such as the introduction of acidic, amine, and sulfonate groups, significantly enhances the hydrophilicity and selectivity of carbon nanotubes, promoting their use in environmental applications, including water and gas purification.The study also evaluates the potential application of carbon nanotubes as adsorbents and catalysts in the petrochemical industry, thus expanding their scope of use.The results of the research indicate that carbon nanotubes synthesized using Cp2Fe2(CO)4 have high performance characteristics and significant potential for use in various environmental and industrial technologies
