Abstract

Methods and systems for electrochemical conversion of carbon dioxide to carboxylic acids, glycols, and carboxylates are disclosed. A method may include, but is not limited to, steps (A) to (D). Step (A) may introduce water to a first compartment of an electrochemical cell. The first compartment may include an anode. Step (B) may introduce carbon dioxide to a second compartment of the electrochemical cell. The second compartment may include a solution of an electrolyte and a cathode. Step (C) may apply an electrical potential between the anode and the cathode in the electrochemical cell sufficient to reduce the carbon dioxide to a carboxylic acid intermediate. Step (D) may contact the carboxylic acid intermediate with hydrogen to produce a reaction product.

Description

technical field [0001] The present invention generally relates to the field of electrochemical reactions, and in particular to a method and / or system for electrochemically preparing carboxylic acid, ethylene glycol and carboxylate from carbon dioxide. Background technique [0002] The burning of fossil fuels in productive activities such as power generation, transportation and production produces billions of tons of carbon dioxide every year. Research since the 1970s has suggested that increasing concentrations of carbon dioxide in the atmosphere may be responsible for global climate change, changes in ocean pH, and other potentially damaging effects. Countries around the world, including the United States, are looking for ways to reduce carbon dioxide emissions. [0003] The mechanism of emission reduction is to convert carbon dioxide into economically useful substances, such as fuels and industrial chemicals. If energy from renewable sources is used to convert carbon dio...
