A carbon dioxide capture structure and a method of making thereof, and a method for removing carbon dioxide from a fluid

A method of making a three-dimensional monolithic carbon dioxide capture structure, the method comprising:

• providing a first material, wherein the first material is a sorbent material comprising a carbon-based sorbent material;
• providing a second material, wherein the second material is an inorganic binder material including potassium silicate;
• providing a solvent;
• mixing the first material, the second material and the solvent to produce a sorbent mixture;
• building a monolithic three-dimensional porous structure using the sorbent mixture as building material;
• and
• treating the monolithic three-dimensional porous structure so as to obtain the carbon dioxide capture structure;
• wherein treating the monolithic three-dimensional porous structure comprises drying the monolithic three-dimensional porous structure at a temperature of at most 150° C.
