Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 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.
