摘要： Electrochemical devices, such as membrane electrode assemblies and electrochemical reactors, are described herein, as well as and methods for the conversion of reactants such as carbon dioxide to value-added products such as ethanol. In certain aspects, the membrane electrode assemblies are configured to allow for distributed pressure along the cathodic side of a membrane electrode assembly is described. The pressure vessel acts as a cathode chamber, both for the feed of reactant carbon dioxide as well as collection of products. The designs described herein improves the safety of high pressure electrochemical carbon dioxide reduction and allows for varied pressures to be used, in order to optimize reaction conditions. Configurations optimized for producing preferred products, such as ethanol, are also described.

摘要： Catalysts and methods for the selective conversion of carbon dioxide and hydrogen into methanol using heat and high pressure in a hydrogenation reactor are disclosed. Key to this process are catalysts, which are comprised of multimetallic, aluminum oxide-supported nanoparticles. In some embodiments of the invention, the catalytic nanoparticles are made from mixtures of zinc and copper, or mixtures of palladium and copper, in different stoichiometric equivalents. In others, stoichiometric additives or dopants are added in order to improve the rate of product formation, improve selectivity, or allow for flow configurations. Methods for the use of these catalysts for the synthesis of methanol, and for the purification of CO2, H2, or CO gas streams by transforming contaminants into liquid methanol are also described.

摘要： Electrochemical devices capable of converting acidic aqueous byproducts of strained yogurt production into value-added materials, as well as methods of making and using these devices, are described herein. Assembly of an electrolytic cell or series of cells that contain an anode that oxidizes organic substances in the aqueous byproduct stream and a cathode that either reduces organic species or water is described. Electrolysis serves to break down the organic matter present in the liquid, such as lactic acid and lactose, as well as aid in the separation of whey protein matter. Gaseous products of this electrolysis process can be either sold or used in waste-to-energy schemes, thereby introducing an environmentally-friendly method for the electrolytic treatment of acid whey.
