摘要： Methods and reactors for electrochemically expanding a parent material and expanded parent materials are described. Current methods of expanding parent materials incompletely-expand parent material, requiring expensive and time-consuming separation of expanded parent material from unexpanded parent materials. This problem is addressed by the methods and reactor for electrochemically expanding a parent material described herein, which during operation maintain electrical connectivity between the parent material and an electrical power source. The resulting materials described herein have a greater proportion of expanded parent material relative to unexpanded parent material compared to those made according to others methods.

摘要： Soot removal process at or inside a synthesis gas- and/or CO-containing gas production apparatus using as feed gases carbon dioxide, steam, hydrogen and/or a hydrocarbon-containing residual gas and using electrical energy in RWGS processes, electrolyses for electrochemical decomposition of carbon dioxide and/or steam, reforming operations and/or synthesis gas production processes with at least one gas production unit, an electrolysis stack and/or a heater-reactor combination for performing an RWGS reaction and at least one cooling sector/recuperator for CO-containing gas and/or synthesis gas, and also a soot removal assembly. Formation of soot can be suppressed or prevented during gas cooling and soot that is nevertheless deposited can be removed again from the heat exchanger surface.

摘要： Methods, apparatuses, and systems related to the electrochemical separation of target gases from gas mixtures are provided. In some cases, a target gas such as carbon dioxide is captured and optionally released using an electrochemical cell (e.g., by bonding to an electroactive species in a reduced state). Some embodiments are particularly useful for selectively capturing the target gas while reacting with little to no oxygen gas that may be present in the gas mixture. Some such embodiments may be useful in applications involving separations from gas mixtures having relatively low concentrations of the target gas, such as direct air capture and ventilated air treatment.

摘要： The present invention relates to the production of graphene from CO2 through electrolysis and exfoliation processes. One embodiment is a method for producing graphene comprising (i) performing electrolysis between an electrolysis anode and an electrolysis cathode in a molten carbonate electrolyte to generate carbon nanomaterial on the cathode, and (ii) electrochemically exfoliating the carbon nanomaterial from a second anode to produce graphene. The exfoliating step produces graphene in high yield than thicker, conventional graphite exfoliation reactions. CO2 can be the sole reactant used to produce the valuable product as graphene. This can incentivize utilization of CO2, and unlike alternative products made from CO2 such as carbon monoxide or other fuels such as methane, use of the graphene product does not release this greenhouse gas back into the atmosphere.

摘要： The disclosure relates to porous Co3O4 nanoparticles which include flocculated amorphous primary nanoparticles, with air pores formed between the amorphous primary nanoparticles. The porous Co3O4 nanoparticles, according to an embodiment of the disclosure, may be in the form of flocculated amorphous primary nanoparticles of 1 nm or less, have a 400 times larger specific surface area than the conventional Co3O4 particles, and address the issue with the expansion of Co3O4 lattices which may arise when the battery is charged or discharged, thereby providing more reliability when applied to batteries.

摘要： A fluidized catalytic cracking unit system includes a fluidized catalytic cracking unit assembly comprising a cracking unit; a reformer-electrolyzer-purifier assembly comprising a reformer-electrolyzer-purifier cell, the reformer-electrolyzer-purifier cell comprising an anode section and a cathode section; and a carbon capture assembly. The anode section of the reformer-electrolyzer-purifier assembly is configured to receive an input stream comprising hydrocarbon gases and water. The cathode section of the reformer-electrolyzer-purifier assembly is configured to produce a cathode exhaust stream comprising oxygen and carbon dioxide. The fluidized catalytic cracking unit assembly is configured to receive the cathode exhaust stream and to produce a flue gas comprising carbon dioxide, water, and less than 5 mole % oxygen. The carbon capture assembly is configured to receive the flue gas from the fluidized catalytic cracking unit assembly, to separate the carbon dioxide contained in the flue gas, and to produce a gas stream that comprises at least 90 mole % carbon dioxide.

摘要： The present disclosure relates to a method for preparing an ordered porous carbon materials with inexpensive carbon black. The method comprises: dispersing carbon black into a concentrated nitric acid to obtain a uniform dispersion; placing the dispersion in a reactor to perform a reaction by a one-step hydrothermal process; and washing and drying the reaction mixture to obtain an ordered porous carbon material in a honeycomb-like arrangement and rich in oxygen defects. The present disclosure also relates to an ordered porous carbon material prepared by the method, a method for electrocatalytically reducing carbon dioxide to formic acid under ambient temperature and atmospheric pressure by using the ordered porous carbon material, and a method for electrocatalytically reducing nitrogen to ammonia under ambient temperature and atmospheric pressure by using the ordered porous carbon material as a supported catalyst.

摘要： An individual solid oxide cell (SOC) constructed of a sandwich configuration including in the following order: an in oxygen electrode, a solid oxide electrolyte, a fuel electrode, a fuel manifold, and at least one layer of mesh. In one embodiment, the mesh supports a reforming catalyst resulting in a solid oxide fuel cell (SOFC) having a reformer embedded therein. The reformer-modified SOFC functions internally to steam reform or partially oxidize a gaseous hydrocarbon, e.g. methane, to a gaseous reformate of hydrogen and carbon monoxide, which is converted in the SOC to water, carbon dioxide, or a mixture thereof, and an electrical current. In another embodiment, an electrical insulator is disposed between the fuel manifold and the mesh resulting in a solid oxide electrolysis cell (SOEC), which functions to electrolyze water and/or carbon dioxide.
