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： A method for preparing hydrogen sulfide from sulfur dioxide by electrochemical reduction includes electrochemically reducing sulfur dioxide absorbed in an aqueous solution into gaseous hydrogen sulfide with a membrane electrode, resulting in efficient and selective conversion of the sulfur dioxide absorbed in the aqueous solution into the hydrogen sulfide to avoid a deactivation of a cathode due to colloidal sulfur produced on the cathode and adhesion onto a surface of the cathode, wherein the method is carried out at ambient temperature and normal pressure without addition of a reducing agent, having no waste salts produced, and is simple in operation, and is convenient for large-scale application.

摘要： A method of substituting an azide for hydrogen bonded to a tertiary carbon atom is provided. A liquid mixture in an oxygen-free environment has spaced-apart carbon and platinum electrodes disposed therein. The liquid mixture includes a solvent, ammonium azide, and a base material having at least one tertiary carbon atom with hydrogen bonded thereto. An electric current is applied to the electrodes where the liquid mixture undergoes a reaction. The electrochemically-induced reaction yields a liquid product and a solid product. The liquid product includes the solvent and a constituent having at least one tertiary carbon atom with an azide bonded thereto.
