Spec: Outer diameter:2-5nm,Length:10-20nm, purity: 99%

Carbon nanohorns have the characteristics of large specific surface area, strong thermal stability, porosity, no metal, and difficulty in fusion. They can also be widely used in adsorption and storage materials, catalyst carriers, drug carriers, supercapacitors, and lithium batteries.

1. Carbon Paste Electrode: CNHs electrochemically activated to form a large number of defects, the edge portion of the oxygen-containing functional groups is more conducive to a high concentration of H2O2 detection, the dahlia shaped aggregation increases the target analyte contact to the active site point, showing a good electrochemical performance H2O2, is expected to replace commonly used platinum electrodes detect H2O2.

2. Biosensors: functional after CNHs can adsorb myoglobin to build electrochemical biosensor to detect H2O2, these sensors exhibit good target analyte sensitivity.

3. The new energy battery: carbon nanohorn can be used in fuel cells electrocatalytic carrier or substrate material, for enhancing polymer electrolyte membrane fuel cell performance. CNHs as carrier particles catalytic metal nanoparticles, a better performance than the traditional black.

4. Electrochemical Capacitors: CNHs / single-wall carbon nanotube composites for high-power supercapacitor power pole, the new composite electrode with high - the large pore volume, which can accommodate more electrolyte, ensuring ion transport, in order to achieve higher power.
