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.
