Single Walled Carbon Nanohorns Application and Characteristics:

1. Single-walled carbon nanohorns is a new single-walled carbon nanotube conductive material, which is by the direct laser ablation of ultra-high purity stone obtained without adding metal catalyst,which can produce high purity and high yield.

2. Single-walled carbon angle nano graphite tube end is tapered, the taper angle of 20 degrees, inner diameter of 2-5nm, a length of 10-20nm,. due to van der Waals forces, the individual single-wall carbon nanotube tends to aggregate to form the corner radius 80 -100nm spherical aggregates, aggregates provide this state of single-walled carbon nano-porestructure characteristics of a variety of angles, angular structure also makes single-walled carbon nanohorns have a lot of defects, compared to some of the substances likely to exhibit high activity, has drawn attention in thehigh-energy fuel cells, gas storage and drug delivery and other studies.

3. It has a high purity, large surface area, is conducive to the development of the advantages of small molecules diffuse structure, making it the field of electro chemistry and chemical analysis has good application prospects.

4. We used single-walled carbon nanohorns in biological sensors, solid-phase micro extraction areas and electronic research catalytic dopamine, vitamin C, uric acid and hydrogen peroxide, etc., and achieved good results, the surface of single-walled carbon nanohorns in electricity chemistry and analytical chemistry has good application prospects.
