Abstract:
Atmospheric water harvesting (AWH) offers a solution for efficiently extracting water from the air. In this protocol, we detail the steps to develop a composite sorbent loaded with hygroscopic salts and lithium chloride (LiCl) and based on hydrogel, acrylamide monomer (AM), and carbon nanotubes (CNTs). We describe a streamlined experimental approach for the synthesis of the honeycomb-optimized hydrogel-based composite adsorbent (PCLG) by in situ polymerization. The produced sorbent exhibits ultra-high adsorption/desorption capacity per unit volume and low-temperature desorption. For complete details on the use and execution of this protocol, please refer to Wang et al. (2022).

01:15Hydrolysis
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...
01:15Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
