Systems and methods are provided for performing a swing adsorption process, such as a temperature swing adsorption process. During portions of a swing cycle where one or more components are being desorbed, a vibration or other perturbation can be induced in the adsorbent and/or in the adsorbent structure to assist with desorption. Inducing a vibration or other perturbation in the adsorbent structure can provide a way to introduce additional energy into the adsorbent system without having to increase the temperature of the adsorbent structure.

A method for regenerating a carbon dioxide (CO.sub.2) sorbent material, the method comprising: (i) contacting a sorbent-CO.sub.2 complex in an aqueous solution containing a reversible photoacid, wherein the CO.sub.2 in the sorbent-CO.sub.2 complex is in the form of bicarbonate, carbonate, or carbamate; and (ii) exposing the aqueous solution to electromagnetic radiation having a wavelength that induces proton release from the photoacid and subsequent protonation of the bicarbonate, carbonate, or carbamate in the sorbent-CO.sub.2 complex to result in release of CO.sub.2 and water and regeneration of the sorbent material. The method may also include re-using the regenerated sorbent to capture carbon dioxide. The sorbent may be, for example, an amino acid (e.g., glycine), alkylamine, alkanolamine, or alkali hydroxide. The reversible photoacid may more particularly be a metastable-state photoacid.

A device comprising a photosensitive sorbent material is configured to concentrate a target chemical species. The photosensitive sorbent material has a stepped Type F-IV isotherm profile with a high working capacity and can adsorb the target chemical species in a porous open phase. The photosensitive material can be converted into a less porous closed phase upon exposure to light of a certain wavelength through a photochemical transformation to allow for desorption and collection of the target chemical species.
