Abstract

A dispersion liquid of the present invention includes: a carbon nanohorn aggregate obtained by aggregating a plurality of single-walled carbon nanohorns in a fibrous form; and a solvent.

Claims (6)

1. A method of manufacturing a gas sensor, comprising:

applying, on a substrate, a dispersion liquid containing a fibrous carbon nanohorn aggregate obtained by aggregating a plurality of single-walled carbon nanohorns in a fibrous form and a solvent; and

forming an adsorbent containing the carbon nanohorn aggregate,

wherein an amount of the fibrous carbon nanohorn aggregate in the dispersion liquid is 0.1 mg to 20 mg per 1 mL of the solvent.

2. The method of manufacturing a gas sensor according to claim 1 , wherein the adsorbent has a thickness of 100 nm to 100 μm.

3. The method of manufacturing a gas sensor according to claim 2 , wherein the absorbent has a thickness of 200 nm to 5 μm.
