Abstract
Official abstract text for this publication.
Provided is an adsorbent for carbon dioxide, including: a graphene oxide layer having an interconnected network structure; and carbon nitride formed on the graphene oxide layer.
First claim
Opening claim text (preview).
What is claimed is: 1. An adsorbent for carbon dioxide comprising: a graphene oxide layer having an interconnected network structure; and carbon nitride formed on the graphene oxide layer. 2. The adsorbent for carbon dioxide of claim 1 , wherein the interconnected network structure is formed by gelling a solution in which the graphene oxide is dispersed. 3. The adsorbent for carbon dioxide of claim 1 , wherein the carbon nitride has a graphitic structure. 4. The adsorbent for carbon dioxide of claim 1 , the adsorbent for carbon dioxide is obtained by mixing the solution in which graphene oxide is dispersed with a nitrogen-containing carbon material, followed by gelling and heat treatment. 5. The adsorbent for carbon dioxide of claim 3 , wherein the carbon nitride is a two-dimensional layered material including hexagonal heptazine(tris-s-triazine) units. 6. The adsorbent for carbon dioxide of claim 1 , wherein the carbon nitride has a condensed polymer structure. 7. The adsorbent for carbon dioxide of claim 6 , wherein the carbon nitride is bound to the graphene oxide layer in the form of monomers forming the polymer structure, and then condensed to form the polymer structure. 8. An adsorbent for carbon dioxide comprising: a graphene oxide layer having an interconnected network structure, the interconnected network structure is formed by gelling a solution in which the graphene oxide is dispersed; and carbon nitride formed on the graphene oxide layer, the carbon nitride has a graphitic structure. 9. The adsorbent for carbon dioxide of claim 8 , wherein the carbon nitride is a two-dimensional layered material including hexagonal heptazine(tris-s-triazine) units. 10. An adsorbent for carbon dioxide comprising: a graphene oxide layer having an interconnected network structure, the interconnected network structure is formed by gelling a solution in which the graphene oxide is dispersed; and carbon nitride formed on the graphene oxide layer, the carbon nitride has a condensed polymer structure. 11. The adsorbent for carbon dioxide of claim 10 , wherein the carbon nitride is bound to the graphene oxide layer in the form of monomers forming the polymer structure, and then condensed to form the polymer structure.
