摘要： Disclosed herein are methods of capturing CO2 from a gas source using electrochemically-enhanced amine capture to form a concentrated CO2 vapor, followed by sequestering CO2 from the concentrated vapor in a sequestration step. The sequestration step includes contacting the concentrated vapor with an aqueous sequestration solution comprising ions capable of forming an insoluble carbonate salt, such that the aqueous sequestration solution comprises the CO2, electrochemically basifying the sequestration solution, thereby precipitating a carbonate solid, separating the carbonate solids from the aqueous sequestration solution or the surface of the mesh.

摘要： An electrolytic cell for polymer electrolyte membrane electrolysis with a cathode half-cell and an anode half-cell is provided. The cathode half-cell and the anode half-cell being separated from one another by a polymer electrolyte membrane. The anodic half-cell has a gas diffusion layer. The gas diffusion layer is made from a fine-meshed metallic carrier material. An anodic catalyst layer with an anodic catalyst material is applied onto the polymer electrolyte membrane. The anodic catalyst layer is arranged adjacent to the gas diffusion layer, wherein a thin protective layer is applied in each case locally and selectively onto the fine-meshed carrier material in the area of the contact points between the gas diffusion layer and the adjoining anodic catalyst layer. The thin protective layer comprises iridium and/or iridium oxide so that the input of anodic catalyst material into the gas diffusion layer is inhibited.

摘要： A method for manufacturing a composite in which at least one of an elemental metal or a metal compound is carried on a carrier. The method includes exposing a dispersion liquid containing a solvent and the carrier to a reduced-pressure environment of less than 80 kPa (absolute pressure) at normal temperature, preparing a raw material mixture liquid by mixing a metal-ion supplying agent which is a metal ion source of the elemental metal or the metal compound with the dispersion liquid, and mixing a reducing agent with the raw material mixture liquid and causing the elemental metal or the metal compound to be carried on a surface of the carrier.

摘要： Electrochemical conversion of nitrate to ammonia is an approach to alleviate nitrate pollution in water and simultaneously generate green NH3 fuels. The practical application of this approach is challenging due to the lack of efficient electrocatalysts. The present disclosure relates generally to an electrocatalyst including a plurality of CuWO4 hollow nanospheres, which include asymmetric oxygen vacancies and adjacent Mo clusters, and methods of making and using the same. The electrocatalyst of the present disclosure is designed for efficient ammonia electrosynthesis.
