Electrocatalysis Used Single-walled Carbon Nanohorns SWCNHs

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

Application for carbon nanohorns:

CNHs mainly in electrocatalysis, electrochemical analysis, the lithium-ion battery materials, electrochemical capacitors, and fuel cell catalyst support metal nanoparticles,etc has important applications.

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.
