Abstract: The preparation method of a gas phase diffusion electrode for electrocatalyzing CO2 to reduce and produce CO provided by the present application comprises: mixing a conductive polymer monomer solution with a molar ratio of 100:1˜1:100 with a metal salt solution, and adding a dispersant to form a mixed solution; transferring the mixed solution to a substrate and reacting at a temperature of −30° C.-50° C. for 1-48 hours to obtain a gas phase diffusion electrode. By the method of using metal ions to self-initiate in-situ growth of conductive polymer monomers, the present application forms a metal-conductive polymer gas phase diffusion electrode. Due to the characteristics of the conductive polymer, the gas phase diffusion electrode can provide more nucleation sites, achieving similar catalytic effect while reducing use amount of metal.

Abstract: In this disclosure, a process of recycling acid, base and the salt reagents required in the Li recovery process is introduced. A membrane electrolysis cell which incorporates an oxygen depolarized cathode is implemented to generate the required chemicals onsite. The system can utilize a portion of the salar brine or other lithium-containing brine or solid waste to generate hydrochloric or sulfuric acid, sodium hydroxide and carbonate salts. Simultaneous generation of acid and base allows for taking advantage of both chemicals during the conventional Li recovery from brines and mineral rocks. The desalinated water can also be used for the washing steps on the recovery process or returned into the evaporation ponds. The method also can be used for the direct conversion of lithium salts to the high value LiOH product. The method does not produce any solid effluent which makes it easy-to-adopt for use in existing industrial Li recovery plants.

Abstract: An electrochemical oxygen pump moves or pumps oxygen molecules with a unique anion conducting layer comprising an anion conducting polymer. These pumps can either be used as high precision oxygen flow meters or as oxygen filters. The system can be plumbed to have air as the inlet and the pump will selectively pump oxygen out, offering another way to remove oxygen from the air, along with distillation or pressure swing absorption.
