Abstract: Described are single-walled metal oxide nanotubes having a plurality of organic functional units or moieties bonded generally in a covalent manner to the inner wall of the single-walled nanotubes. Functionalization of the single-walled metal oxide nanotubes is performed in a single-step during synthesis of the nanotubes. The organic functional units are found dispersed throughout the length of the inner wall and not sterically hindered or contained at only the mouth or ends of the single-walled metal oxide nanotubes.

Abstract: A tunable species removal media including a polymer-impregnated porous material with the introduction of heteroatoms into the porous material during the synthesis of the oxide support. The polymer can be poly(ethyleneimine) (PEI), the porous material a framework of silica nanoparticles, and the heteroatoms selected from Zr, Ti, Fe, Ce, Al, B, Ga, Co, Ca, P, and Ni. The media has a CO2 adsorption of greater than 0.19 mmol CO2/g when exposed to a 400 ppm CO2/Ar flow at a rate of 100 mL/min, and can also have a CO2 adsorption of greater than 0.65 mmol CO2/g when exposed to a 10% CO2/Ar flow at a rate of 100 mL/min. The media can have a heteroatom/Si molar ratio greater than or equal to 0.002.

Abstract: The present disclosure is directed towards sorbents, contactors, methods of using sorbents or contactors to capture CO2, and systems and devices using the sorbents or contactors to capture CO2. The methods, systems, contactors, and sorbents of the present disclosure can be advantageous over current technologies since they are relatively more robust and reduce the cost of capturing CO2, in particular from ambient air.

Abstract: Supported amine polymer adsorbents based on polymers containing only or primarily primary amines sites are to be used as regenerable adsorbents for CO2 capture from ultra-dilute gas streams, such as ambient air, or from mixtures of gases containing preferably at least I 0% oxygen. and can also be useful for use at the moderate gas pressures found in typical post-combustion capture processes, such as flue gas from large point sources such as coal-fired power plants. Preferred supported solid amine adsorbents of this invention are based on poly(allylamine) (“PAA”) and poly(vinyl amine) (“PVAm”), both of which are linear polymers, and their derivatives, containing substantially all primary amine groups, supported on substrates. Preferred such substrates include silica mesocellular foam (MCF) and mesoporous-.gamma.-alumina, as well on mesoporous-.gamma.-alumina coated throughout the pores of MCF, most preferably of monolithic structure. Preferred derivatives include the guanidinylated and cross-linked poly(allylamine) materials.
