Single Wall Carbon Nanohorns

Product Name

^{Name: Single wall carbon nanohorns}

Product Overview

 

^{Single walled carbon nanohorns have a quasi spherical or conical structure, consisting of a single layer of carbon atoms arranged in a hexagonal pattern similar to graphite.}

^{The tip of single-walled carbon nanohorns is a curved structure composed of pentagonal and hexagonal rings of carbon atoms.}

^{Compared with other carbon nanomaterials such as carbon nanotubes, single-walled carbon nanohorns do not have obvious long axes and have a more compact overall structure. The surface of single-walled carbon nanohorns has high chemical activity, mainly due to the special structure of their tips and the presence of a large number of edge carbon atoms.}

^{These surface carbon atoms can react with other chemical substances, such as undergoing chemical modifications such as oxidation, hydrogenation, grafting polymers, etc.}

^{Through surface chemical modification, the surface properties of single-walled carbon nanohorns can be altered, such as hydrophilicity, hydrophobicity, biocompatibility, etc., thereby expanding their application fields.}

^{Under certain conditions, single-walled carbon nanohorns exhibit good chemical stability.}

^{It is relatively stable at room temperature and pressure, and is not prone to violent reactions with oxygen, moisture, and other substances in the air.}

^{However, under extreme conditions such as high temperature, strong acid, and strong alkali, its structure and properties may undergo changes. For example, structural transformations such as graphitization may occur at high temperatures, and the surface may be corroded or undergo chemical reactions in strong acid or alkali environments.}

^{Product Features}

 

^{Electrical properties: Due to its unique electronic structure, single-walled carbon nanohorns have excellent conductivity. Similar to carbon nanotubes, they can exhibit metallic or semiconductor conductivity, depending on factors such as their structure and diameter.}

^{Mechanical properties: Single walled carbon nanohorns have high strength and stiffness. The covalent bonding between its carbon atoms gives the material excellent mechanical stability, allowing it to withstand large external forces without significant deformation or damage. This mechanical property makes it have potential application prospects in enhancing composite materials, such as being added as a reinforcing phase to polymers and other materials to improve their mechanical properties.}

^{Optical performance: Single walled carbon nanohorns exhibit unique optical properties under certain excitation conditions. In theory, it can generate fluorescence phenomena, and its fluorescence emission wavelength and intensity are related to factors such as the size, structure, and surface state of carbon nanohorns. This optical property makes it potentially applicable in fields such as biological imaging and optoelectronic devices, such as serving as a fluorescent marker for labeling and imaging of biological cells.}

^{Application Fields}

 

^{Electrochemistry: Due to the excellent electronic properties and high specific surface area of single-walled carbon nanohorns, they are widely used in electrochemical research, such as modifying electrodes to improve electrochemical reaction efficiency.}

^{Adsorption and storage: As an adsorbent, single-walled carbon nanohorns can theoretically adsorb rare gases such as hydrogen and xenon, as well as liquids such as water, benzene, and ethanol. After nitric acid treatment, the pore capacity inside and between it significantly increases, making it suitable for storing supercritical methane and other substances.}

^{Catalyst carrier: Synthesizing uniform nanoparticles on single-walled carbon nanohorns can make it an efficient catalyst carrier. Its unique structure helps to enhance the durability of the catalyst.}

^{Drug carrier: Single walled carbon nanohorns have a large specific surface area and numerous corner voids, which can adsorb a large number of molecules, making them an ideal drug carrier. Its characteristic of not containing metal impurities avoids cytotoxicity and is easy to accumulate near tumor tissue, improving anti-tumor efficiency.}

^{Biosensors: Single walled carbon nanohorns do not contain metal impurities, so they can be applied to the research of biosensors without pre-treatment. Scientists have used it to construct various biosensors.}

^{In the field of energy, composite materials of single-walled carbon nanohorns and metal oxides can be used as anode materials for lithium-ion batteries to improve battery performance; SWCNHs doped with MgB2 exhibit magnetism and have the potential to become a new superconducting material.}
