摘要： A method of capturing carbon dioxide (CO2) present in air is provided. The method includes adding a carbon-dioxide-capturing device to a heating, ventilation, and air conditioning (HVAC) system of a building. The carbon-dioxide-capturing device is added to one or both of an air handler and air-distribution ductwork of the HVAC system. The method further includes circulating air including carbon dioxide through the carbon-dioxide-capturing device in the HVAC system. A direct decarbonization system for capturing carbon dioxide present in air is also provided. The system includes an HVAC unit, air-distribution ductwork connected to the HVAC unit, and a carbon-dioxide-capturing device disposed in one or both of the HVAC unit and the air-distribution ductwork. Carbon dioxide gas present in air passing through the HVAC unit or the air-distribution ductwork is removable from the air by the carbon-dioxide-capturing device.

摘要： An encapsulated fiber composition (typically resulting from an electrospinning process) containing: (i) a lengthwise core portion of the fiber comprising an amine-containing material for adsorbing carbon dioxide; and (ii) a lengthwise sheath portion of the fiber surrounding said lengthwise core portion, wherein the lengthwise sheath portion comprises a microporous polymer. Particularly described are fiber compositions containing a nanoparticle organic hybrid material (NOHM) or organoamine or amine-containing sorbent (e.g., PEI or TEPA) in a core portion of the fiber and a polymer of intrinsic microporosity (PIM), such as PIM-1 or PIM-2, or PAN or PAN combined with a polysilazane or polysiloxane in a sheath portion of the fiber. A method of using the fiber composition to capture carbon dioxide, such as from ambient air, is also described.

摘要： A catalytic carbon capture material is provided. The catalytic carbon capture material includes a microporous polymer including a Tröger's base moiety, and a transition metal is coordinated within the microporous polymer. The catalytic carbon capture material selectively captures carbon dioxide (CO2) and also is a catalyst that simultaneously converts the captured carbon dioxide into one or more carbon dioxide-based products. A method of making the catalytic carbon capture material and a method of selective carbon dioxide capture and conversion are also provided.

摘要： A method of ethanol conversion to higher carbon compounds is provided. The method includes feeding a reactant to a reactor, the reactant including ethanol. The reactant may further include water in the form of steam. The reactant is introduced to a perovskite catalyst in the reactor. The perovskite catalyst promotes the formation of the higher carbon compounds from ethanol, and may be in the form of a powder or thin film. The perovskite catalyst has the formula ABO3, wherein A is one or more selected from a group consisting of La and Sr, and wherein B is one or more selected from a group consisting of Mn, Ca, Fe, and Co. The perovskite catalyst particularly may be La0.7Sr0.3MnO3. The obtained higher carbon compounds may include at least one of acetone and crotonaldehyde.
