## Abstract

Described herein are solid sorbents including amines that are covalently bonded to a porous support. The solid sorbents exhibit high adsorption capacities for carbon dioxide. The solid sorbents exhibit desirable hydrothermal and cycling stability.

## Claims

### Claim 1

A system comprising:
a substrate;
at least one particle;
at least one binder material; and
at least one amine-containing unit, wherein the amine-containing unit is not covalently bonded to the at least one particle.

### Claim 2 (depends on 1)

The system of claim 1, wherein the at least one amine-containing unit comprises two or more amine groups.

### Claim 3 (depends on 1)

The system of claim 1, wherein the second amine-containing unit comprises an oligomer, a polymer, a small molecule, or a mixture thereof.

### Claim 4 (depends on 1)

The system of claim 1, wherein the at least one amine-containing unit does not comprise tertiary amines.

### Claim 5 (depends on 1)

The system of claim 1, wherein the at least one amine-containing unit comprises only primary amines.

### Claim 6 (depends on 1)

The system of claim 1, wherein the at least one amine-containing unit comprises at least one primary amine, at least one secondary amine, and at least one tertiary amine.

### Claim 7

A system comprising:
a substrate;
at least one binder material;
at least one sorbent, wherein the at least one sorbent comprises a support and at least one amine-containing unit, wherein the at least one amine-containing unit is covalently bonded to the support.

### Claim 8 (depends on 7)

The system of claim 7, wherein the at least one amine-containing unit comprises two or more amine groups.

### Claim 9 (depends on 7)

The system of claim 7, wherein the second amine-containing unit comprises an oligomer, a polymer, a small molecule, or a mixture thereof.

### Claim 10 (depends on 7)

The system of claim 7, wherein the at least one amine-containing unit does not comprise tertiary amines.

### Claim 11 (depends on 7)

The system of claim 7, wherein the at least one amine-containing unit comprises at least one primary amine and at least one secondary amine.

### Claim 12 (depends on 7)

The system of claim 7, wherein the at least one amine-containing unit comprises at least one primary amine, at least one secondary amine, and at least one tertiary amine.

### Claim 13 (depends on 7)

### Claim 14

A system comprising:
a substrate;
at least one binder material;
at least one sorbent, wherein the at least one sorbent comprises a support, a first amine-containing unit covalently bonded to the support, and a second amine-containing unit not covalently bonded to the support; and
optionally a cross-linking moiety, wherein the cross-linking moiety can react with the first amine-containing unit or the second amine-containing unit.

### Claim 15 (depends on 14)

The system of claim 14, wherein the second amine-containing unit is at least partially self cross-linked through the cross-linking moiety.

### Claim 16 (depends on 14)

The system of claim 14, wherein the first amine-containing unit and second the amine-containing unit are at least partially covalently bonded through the cross-linking moiety.
